Understanding the Problem: Candy, Guests, and Radicals

So, let's set the scene, shall we? Our main character, Brooklyn, is having a party, and she's got a serious amount of candy. We're talking 108q10\sqrt{108 q^{10}} pieces of candy. Now, Brooklyn is a generous soul, and she wants to share this bounty equally with her guests. The twist? The number of guests isn't a simple number either; it's 3q\sqrt{3 q} guests. The big question we need to answer is: How much candy does each guest get? This is where the magic of mathematics, specifically simplifying radical expressions, comes into play. To solve this, we need to divide the total amount of candy by the number of guests. Mathematically, this looks like 108q103q\frac{\sqrt{108 q^{10}}}{\sqrt{3 q}}. On the surface, it might seem a bit hairy with those square roots and variables, but fear not! We're going to dissect this step-by-step, simplifying each radical expression involved. This problem is a perfect illustration of how algebraic concepts, like radicals and division, are used in real-world (or at least, party-world!) scenarios. We'll be using properties of exponents and radicals to simplify the expression, making it easy to see the final amount of candy each guest receives. So, let's get our mathematical hats on and figure out this sweet deal!

Step 1: Simplifying the Total Candy Expression

Alright, party people, let's kick things off by tackling the total amount of candy Brooklyn has: 108q10\sqrt{108 q^{10}}. Before we can even think about dividing, we need to simplify this radical expression as much as possible. The goal here is to pull out any perfect squares from under the square root sign. For 108\sqrt{108}, we need to find the largest perfect square that divides 108. Let's think about factors: 4 goes into 108 (108 = 4 * 27), 9 goes into 108 (108 = 9 * 12), and even 36 goes into 108 (108 = 36 * 3)! Since 36 is the largest perfect square factor, we can rewrite 108\sqrt{108} as 36Γ—3\sqrt{36 \times 3}. Using the property of radicals ab=aΓ—b\sqrt{ab} = \sqrt{a} \times \sqrt{b}, this becomes 36Γ—3\sqrt{36} \times \sqrt{3}, which simplifies to 636\sqrt{3}.

Now, let's look at the variable part: q10q^{10}. Remember that a square root is essentially the same as raising something to the power of 1/2. So, q10\sqrt{q^{10}} is the same as (q10)1/2(q^{10})^{1/2}. Using the power of a power rule for exponents, (am)n=amΓ—n(a^m)^n = a^{m \times n}, we get q10Γ—(1/2)=q5q^{10 \times (1/2)} = q^5. So, q10\sqrt{q^{10}} simplifies to q5q^5.

Putting it all together, the total amount of candy, 108q10\sqrt{108 q^{10}}, simplifies to 63q56\sqrt{3} q^5. This is a much cleaner expression to work with! This simplification process is key in algebraic manipulation, allowing us to handle complex expressions more effectively. By breaking down the number and the variable separately, we can systematically reduce the complexity. It’s like tidying up before you start a big project – makes everything so much easier!

Step 2: Simplifying the Number of Guests Expression

Next up on our candy-sharing adventure, let's simplify the expression for the number of guests: 3q\sqrt{3 q}. This expression is already pretty simple, but we need to make sure we understand its components. The number 3 doesn't have any perfect square factors other than 1, so 3\sqrt{3} cannot be simplified further on its own. Similarly, the variable qq is raised to the power of 1, and we can't simplify q\sqrt{q} any further unless we know more about qq. So, for now, 3q\sqrt{3 q} remains as it is. This is important because when we combine it with the simplified candy expression, we'll see how these terms interact. Understanding radical forms is crucial here; we only simplify if there are perfect square factors. In this case, there aren't any obvious ones, so we leave it as is. This step highlights that not all radical expressions can be simplified dramatically, but it's always worth checking! We're getting closer to figuring out how much candy each guest gets, and this simplification, even if minimal, prepares us for the final division.

Step 3: Dividing the Candy Among Guests

Now for the grand finale, guys! We need to find out how much candy each guest gets. To do this, we divide the total amount of candy by the number of guests. Using our simplified expressions, this division is:

63q53q \frac{6\sqrt{3} q^5}{\sqrt{3 q}}

To tackle this, we can use the property of radicals that states ab=ab\frac{\sqrt{a}}{\sqrt{b}} = \sqrt{\frac{a}{b}}. So, we can combine the terms under a single square root:

63q53q 6 \sqrt{\frac{3 q^5}{3 q}}

Now, we simplify the fraction inside the square root. The 3s cancel out, and we use the rule for dividing exponents with the same base, which is aman=amβˆ’n\frac{a^m}{a^n} = a^{m-n}. So, q5q1=q5βˆ’1=q4\frac{q^5}{q^1} = q^{5-1} = q^4.

Our expression now becomes:

6q4 6 \sqrt{q^4}

Finally, we simplify q4\sqrt{q^4}. Just like we saw before, q10=q5\sqrt{q^{10}} = q^5, we can see that q4=q4/2=q2\sqrt{q^4} = q^{4/2} = q^2.

So, the final answer is:

6q2 6 q^2

This means each guest gets 6q26q^2 pieces of candy. Pretty neat, right? Dividing algebraic expressions can seem daunting, but by applying the rules of exponents and radicals systematically, we can simplify even complex fractions like this one into a straightforward answer. It's all about breaking down the problem into manageable steps and using the properties you've learned.

Conclusion: Sweet Success with Math!

And there you have it, math enthusiasts! We've successfully navigated through a problem involving simplifying radical expressions and dividing algebraic terms. Brooklyn's party situation, with 108q10\sqrt{108 q^{10}} pieces of candy shared among 3q\sqrt{3 q} guests, resulted in each guest receiving a cool 6q26q^2 pieces. This journey through radicals and variables wasn't just about solving a puzzle; it was a practical demonstration of how mathematical rules work together. Remember, the key is to simplify each part of the expression first – whether it's the number under the radical or the variable part. Then, you can combine and divide using the properties of exponents and radicals.

Don't get discouraged by complex-looking problems. Break them down, apply the rules you know, and you'll find that most of them become much more manageable. This kind of problem-solving in mathematics is a skill that benefits you far beyond the classroom. It teaches you to think logically, systematically, and creatively. So next time you see a problem with radicals, think of Brooklyn and her candy – you've got this! Keep practicing, keep exploring, and most importantly, keep enjoying the power and elegance of mathematics. Happy calculating, everyone!
