Math isn't just about memorizing formulas; it's about developing a way of thinking that can help you solve problems in all areas of life. So, let’s put on our thinking caps and get started! Let’s begin by dissecting the expression and understanding the order of operations we need to follow. Remember the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction)? It's our trusty guide in the world of mathematical calculations. First up, we'll deal with the exponents, then the multiplication, and finally, we'll consider the "per 15 minutes" part. This problem is a fantastic blend of exponents and negative powers, so understanding these concepts thoroughly will be key. We'll also touch on how to interpret the final result in the context of the time frame given (15 minutes). So, buckle up, grab a pen and paper, and let's embark on this mathematical adventure together!

Breaking Down the Expression: The Power of Exponents

So, when we first see the expression (3²)³x5⁻², the first thing that probably catches our eye is the exponents, right? Exponents are a fundamental concept in math, and understanding them is crucial for solving this problem. Let's start with the term (3²)³. This is where the power of a power rule comes into play. Remember, when you have an exponent raised to another exponent, you multiply the exponents. In simpler terms, (a^m)n is the same as a^(mn). This is a key rule that we'll use frequently, so make sure you've got it down! Applying this rule to our problem, (3²)³ becomes 3^(23), which simplifies to 3⁶. Now, what does 3⁶ actually mean? It means 3 multiplied by itself six times: 3 * 3 * 3 * 3 * 3 * 3. If we calculate that, we get 729. So, the first part of our expression, (3²)³, is equal to a whopping 729! It’s amazing how quickly these exponential numbers grow, isn't it? Understanding this concept is so important because exponents show up everywhere in math and science. From calculating compound interest to understanding the scale of the universe, exponents are our friends. But we're not done yet! We still have the 5⁻² part to tackle. This introduces us to the concept of negative exponents. Negative exponents can seem a bit tricky at first, but they're actually quite straightforward once you understand the rule. A negative exponent means we're dealing with the reciprocal of the base raised to the positive exponent. In other words, a⁻ⁿ is the same as 1/aⁿ. So, 5⁻² is the same as 1/5². And what is 5²? It's simply 5 * 5, which equals 25. Therefore, 5⁻² is equal to 1/25. See? Not so scary after all! Now we've successfully broken down the exponential parts of our expression. We've transformed (3²)³ into 729 and 5⁻² into 1/25. We’re making great progress! In the next step, we'll see how these pieces fit together when we perform the multiplication operation. Stay tuned, and let's keep this mathematical momentum going!

Multiplying and Simplifying: Putting the Pieces Together

Alright, guys, now that we've conquered the exponents, it's time to bring everything together and perform the multiplication. Remember, we've simplified (3²)³ to 729 and 5⁻² to 1/25. So, our expression now looks like this: 729 * (1/25). This step is all about combining these values to get a single result. Multiplying 729 by 1/25 is the same as dividing 729 by 25. Think of it like sharing 729 cookies among 25 friends – each friend gets a fraction of the total cookies. To do this division, we can either use a calculator or perform long division. If we divide 729 by 25, we get 29.16. So, the value of the expression (3²)³x5⁻² is 29.16. We’ve successfully navigated the exponents and the multiplication, and we're one step closer to solving the entire problem! But hold on, we're not quite finished yet. The original question includes the phrase "per 15 minutes." This means we need to consider this result in the context of a specific time frame. The "per 15 minutes" part tells us that 29.16 is the result for every 15-minute interval. This is an important piece of information because it adds a real-world dimension to our calculation. It could represent something like the amount of a substance produced in a chemical reaction every 15 minutes, or the number of tasks completed by a machine in that time. To fully understand the problem, we might want to know the result over a longer period, like an hour or a day. To do that, we would need to scale up our result accordingly. For example, there are four 15-minute intervals in an hour (60 minutes / 15 minutes = 4). So, if we wanted to know the result per hour, we would multiply 29.16 by 4. That gives us 116.64 per hour. See how the "per 15 minutes" detail changes the way we interpret our result? It's a crucial part of the problem, and it highlights the importance of paying attention to all the information given. In the next section, we'll explore this "per 15 minutes" concept in more detail and discuss how we can apply it to different scenarios. So, let's keep going and unravel the final layer of this mathematical puzzle!

Interpreting "Per 15 Minutes": Context is Key

Okay, so we've crunched the numbers and found that (3²)³x5⁻² equals 29.16. But remember, the question specifically asks for this result "per 15 minutes." This little phrase adds a whole new layer of meaning to our answer, and it’s super important that we understand what it implies. The term “per” is a mathematical way of saying “for each” or “for every.” So, “29.16 per 15 minutes” means that for every 15-minute interval, we have a result of 29.16. Think of it like this: imagine you're baking cookies, and you find that you can bake 29.16 cookies every 15 minutes (let's just pretend you can bake fractions of cookies for the sake of the example!). This rate of cookie production is consistent within each 15-minute period. Now, let's think about how this “per 15 minutes” concept can be applied in different real-world scenarios. Imagine a factory producing gadgets. If the production rate is 29.16 gadgets per 15 minutes, we can use this information to calculate the production rate over longer periods, like an hour or a day. As we discussed earlier, there are four 15-minute intervals in an hour. So, to find the hourly production, we would multiply 29.16 by 4, giving us 116.64 gadgets per hour. This kind of calculation is crucial for businesses to plan production schedules and estimate output. Another example could be in the context of chemical reactions. If a reaction produces 29.16 units of a substance every 15 minutes, scientists can use this rate to predict how much substance will be produced over a longer duration. This is vital for controlling chemical processes and ensuring desired outcomes. The “per 15 minutes” concept can also be applied to rates of change in various fields, such as finance or population growth. For instance, if an investment grows by 29.16 units every 15 minutes (which would be an incredibly rapid growth rate!), we can use this to project the growth over days, months, or even years. Understanding the context is absolutely key when dealing with “per” rates. It helps us to interpret the result in a meaningful way and apply it to real-world situations. The “per 15 minutes” part of the problem isn't just a detail; it's a crucial piece of the puzzle that helps us understand the bigger picture. In the next section, we'll wrap up our discussion and summarize the key steps we took to solve this problem. So, keep that mathematical brain buzzing and let's finish strong!

First, we broke down the expression step by step, focusing on the order of operations. We remembered PEMDAS – Parentheses, Exponents, Multiplication and Division, Addition and Subtraction – our trusty guide for mathematical calculations. We started by simplifying the exponents. We learned the power of a power rule, which helped us transform (3²)³ into 3⁶. We then calculated 3⁶, which gave us 729. Next, we tackled the negative exponent 5⁻². We learned that a negative exponent means we're dealing with the reciprocal of the base raised to the positive exponent. So, 5⁻² became 1/5², which simplified to 1/25. With the exponents handled, we moved on to multiplication. We multiplied 729 by 1/25, which is the same as dividing 729 by 25. This gave us a result of 29.16. But we didn't stop there! We remembered the crucial phrase “per 15 minutes” in the original question. We understood that this meant our result, 29.16, was the value for every 15-minute interval. We discussed how this “per” concept applies to real-world scenarios, such as manufacturing, chemical reactions, and even finance. We saw how understanding the context is vital for interpreting the result meaningfully and applying it to different situations. We even explored how to scale up the result to calculate values over longer periods, like hours or days.
