Introduction

In mathematics, simplifying expressions is a crucial skill that helps us solve problems efficiently and accurately. One of the most common types of expressions that require simplification is square roots. In this article, we will focus on simplifying the expression $\sqrt{512 m^3}$ .

Understanding Square Roots

Before we dive into simplifying the expression, let's quickly review what square roots are. A square root of a number is a value that, when multiplied by itself, gives the original number. For example, the square root of 16 is 4, because 4 multiplied by 4 equals 16. We can represent square roots using the symbol $\sqrt{}$ . For instance, $\sqrt{16}$ means the square root of 16.

Breaking Down the Expression

To simplify the expression $\sqrt{512 m^3}$ , we need to break it down into its prime factors. The number 512 can be expressed as $2^9$ , because $2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 = 512$ . The variable $m^3$ represents a cube of meters, which can be expressed as $m \times m \times m$ .

Simplifying the Expression

Now that we have broken down the expression into its prime factors, we can simplify it. We can rewrite the expression as $\sqrt{2^9 m^3}$ . Since the square root of a product is equal to the product of the square roots, we can rewrite the expression as $\sqrt{2^9} \times \sqrt{m^3}$ .

Simplifying the Square Root of 2^9

The square root of $2^9$ can be simplified by taking the square root of the exponent. This means that we can rewrite $\sqrt{2^9}$ as $2^{9/2}$ . Since $9/2$ can be simplified to $4.5$ , we can rewrite the expression as $2^{4.5}$ .

Simplifying the Square Root of m^3

The square root of $m^3$ can be simplified by taking the square root of the exponent. This means that we can rewrite $\sqrt{m^3}$ as $m^{3/2}$ . Since $3/2$ can be simplified to $1.5$ , we can rewrite the expression as $m^{1.5}$ .

Combining the Simplified Expressions

Now that we have simplified the square roots of $2^9$ and $m^3$ , we can combine them to get the final simplified expression. We can rewrite the expression as $2^{4.5} \times m^{1.5}$ .

Conclusion

In this article, we simplified the expression $\sqrt{512 m^3}$ by breaking it down into its prime factors and simplifying the square roots. We rewrote the expression as $2^{4.5} \times m^{1.5}$ , which is the final simplified form of the expression.

Final Answer

The final answer is $\boxed{2^{4.5} \times m^{1.5}}$ .
