Understanding the Problem

When dealing with expressions involving square roots, it's essential to simplify them to make calculations easier. The given expression is $-4 \sqrt{32 x^3}$, and our goal is to simplify it. To start, we need to understand the properties of square roots and how to manipulate them.

Properties of Square Roots

The 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 also extend this concept to expressions involving variables. The square root of a variable expression is a value that, when multiplied by itself, gives the original expression.

Simplifying the Expression

To simplify the expression $-4 \sqrt{32 x^3}$, we need to start by simplifying the expression inside the square root. The expression inside the square root is $32 x^3$. We can simplify this expression by factoring out perfect squares.

Factoring Perfect Squares

A perfect square is a number that can be expressed as the product of an integer and itself. For example, 16 is a perfect square because it can be expressed as 4 multiplied by 4. We can also extend this concept to expressions involving variables. A perfect square expression is an expression that can be expressed as the product of a variable and itself.

Simplifying $32 x^3$

To simplify $32 x^3$, we need to factor out perfect squares. We can start by breaking down 32 into its prime factors. 32 can be expressed as 2 multiplied by 2 multiplied by 2 multiplied by 2 multiplied by 2, or $2^5$. Therefore, we can rewrite $32 x^3$ as $2^5 x^3$.

Simplifying $2^5 x^3$
