Finding The Equivalent Expression Of 10√5 A Step-by-Step Guide

In the realm of mathematics, particularly when dealing with radicals and square roots, it's crucial to understand how different expressions can represent the same value. This question challenges our ability to manipulate radical expressions and identify equivalent forms. Let's embark on a journey to dissect the expression $10\sqrt{5}$ and uncover its true mathematical identity. The core concept here revolves around the properties of square roots and how we can move coefficients inside the radical sign. To find an equivalent expression, we need to understand how to rewrite the given expression by bringing the coefficient '10' inside the square root. This involves squaring the coefficient and then multiplying it by the radicand (the number inside the square root). The question at hand asks us to identify which of the provided options—A. $\sqrt{500}$, B. $\sqrt{105}$, C. $\sqrt{50}$, or D. $\sqrt{15}$—is mathematically equivalent to the expression $10\sqrt{5}$. This seemingly simple question tests our understanding of how to manipulate radical expressions and identify equivalent forms. It’s a fundamental skill in algebra and is crucial for simplifying more complex mathematical problems. Before diving into the solution, it’s important to refresh our understanding of square roots and their properties. A square root of a number is a value that, when multiplied by itself, gives the original number. For example, the square root of 9 is 3 because 3 * 3 = 9. Understanding this basic concept is crucial for working with radical expressions. Moreover, the property of radicals that allows us to move coefficients inside the square root is key to solving this problem. This property states that $a\sqrt{b} = \sqrt{a^2 * b}$. In other words, we can bring a number outside the square root inside by squaring it and then multiplying it by the number already inside the square root. This property is the cornerstone of simplifying and comparing radical expressions, and it's the key to unlocking the mystery of this particular question. The challenge lies in applying this property correctly and then comparing the resulting expression with the given options. So, let's sharpen our pencils and delve into the heart of the problem, unraveling the equivalent expression of $10\sqrt{5}$ step by step.

Deconstructing $10\sqrt{5}$: How to Simplify Radical Expressions

The journey to finding the equivalent expression begins with a careful deconstruction of the given expression, $10\sqrt{5}$. Our mission is to transform this expression into a form where the coefficient 10 is integrated into the square root, allowing us to compare it directly with the options provided. The fundamental principle we'll employ here is the property of radicals that allows us to move a coefficient inside the square root by squaring it. This is based on the understanding that a number multiplied by a square root can be rewritten by bringing the number inside the root as its square. This transformation is not just a mathematical trick; it's a reflection of the underlying properties of square roots and exponents. When we square a number, we are essentially multiplying it by itself. And when we take the square root of a number, we are finding a value that, when multiplied by itself, equals the original number. This inverse relationship between squaring and taking the square root is what allows us to move numbers in and out of the radical sign. Now, let's apply this principle to our expression. The coefficient 10, standing proudly outside the square root, needs to be brought inside. To do this, we square it: $10^2 = 10 * 10 = 100$. This result, 100, will now be multiplied by the radicand, which is the number inside the square root, in this case, 5. The process of squaring the coefficient and multiplying it by the radicand is the heart of simplifying radical expressions. It allows us to consolidate the expression under a single square root, making it easier to compare with other expressions. This technique is not only useful for this particular problem but is also a valuable tool in various mathematical contexts, including simplifying complex algebraic expressions and solving equations involving radicals. The next step is to perform the multiplication: $100 * 5 = 500$. This gives us the number that will reside inside the square root. We've successfully transformed the coefficient into a part of the radicand. Now, we have a new expression that is mathematically equivalent to the original but presented in a different form. This new form will allow us to directly compare our result with the options provided in the question. This transformation is a testament to the flexibility of mathematical notation and the power of understanding fundamental properties. So, after applying the principle of moving the coefficient inside the square root, we have arrived at a crucial juncture in our problem-solving journey. We are now poised to identify the correct answer by comparing our simplified expression with the given options.

Solving the Puzzle: Identifying the Equivalent Expression

Having successfully transformed $10\sqrt{5}$ into a form where the coefficient is integrated into the square root, we now stand at the threshold of solving our puzzle. Our transformed expression is $\sqrt{100 * 5}$, which simplifies to $\sqrt{500}$. This is the key that unlocks the answer to our question. Now, let's carefully examine the options presented and compare them with our simplified expression: A. $\sqrt{500}$ B. $\sqrt{105}$ C. $\sqrt{50}$ D. $\sqrt{15}$ The process of comparing expressions is a fundamental skill in mathematics, and it often involves simplifying expressions to their most basic forms. In this case, we've already done the hard work of simplifying our original expression, making the comparison straightforward. We are looking for an option that is mathematically identical to $\sqrt{500}$. A quick glance reveals that option A, $\sqrt{500}$, is a direct match. This is the moment of truth, the culmination of our step-by-step journey. Option A aligns perfectly with our simplified expression, confirming its equivalence to the original expression, $10\sqrt{5}$. The other options, B, C, and D, represent different numerical values under the square root and are therefore not equivalent to our original expression. Option B, $\sqrt{105}$, is significantly smaller than $\sqrt{500}$. Option C, $\sqrt{50}$, is also considerably smaller. And option D, $\sqrt{15}$, is the smallest of the lot. These discrepancies highlight the importance of careful calculation and comparison when dealing with mathematical expressions. This exercise is not just about finding the right answer; it's about developing a deeper understanding of mathematical relationships and honing our problem-solving skills. The ability to manipulate expressions, simplify them, and compare them is a crucial skill in mathematics and beyond. So, with confidence and clarity, we can declare that option A, $\sqrt{500}$, is indeed the expression equivalent to $10\sqrt{5}$. Our journey through the world of radicals has led us to a definitive answer, showcasing the power of mathematical reasoning and the elegance of equivalent expressions.

The process of arriving at the correct answer is just as important as the answer itself. It demonstrates our understanding of the underlying mathematical principles and our ability to apply them effectively. In this case, we utilized the property of radicals that allows us to move a coefficient inside the square root by squaring it and multiplying it by the radicand. This transformation is a powerful tool in simplifying and comparing radical expressions. Understanding why A is correct also involves understanding why the other options are incorrect. Options B, C, and D—$\sqrt{105}$, $\sqrt{50}$, and $\sqrt{15}$, respectively—do not hold the same numerical value as $10\sqrt{5}$.
