Simplify $\sqrt{256 X^4}$.

$$

Understanding the Problem

When dealing with square roots, it's essential to simplify the expression to make it easier to work with. In this case, we're given the expression $\sqrt{256 x^4}$, and our goal is to simplify it. To start, let's break down the expression into its prime factors.

Breaking Down the Expression

The expression $\sqrt{256 x^4}$ can be broken down into two parts: $\sqrt{256}$ and $\sqrt{x^4}$. We can simplify each part separately.

Simplifying $\sqrt{256}$

To simplify $\sqrt{256}$, we need to find the prime factors of 256. We can start by dividing 256 by 2, which gives us 128. We can continue dividing by 2 until we reach 1.

256 ÷ 2 = 128
128 ÷ 2 = 64
64 ÷ 2 = 32
32 ÷ 2 = 16
16 ÷ 2 = 8
8 ÷ 2 = 4
4 ÷ 2 = 2
2 ÷ 2 = 1

Now that we have the prime factors of 256, we can rewrite it as $2^8$. Therefore, $\sqrt{256}$ can be simplified to $2^4$, which is equal to 16.

Simplifying $\sqrt{x^4}$

To simplify $\sqrt{x^4}$, we can use the property of exponents that states $\sqrt{x^n} = x^{n/2}$. Applying this property to $\sqrt{x^4}$, we get $x^2$.

Combining the Simplified Expressions

Now that we have simplified both parts of the expression, we can combine them to get the final simplified expression.

$\sqrt{256 x^4} = \sqrt{256} \cdot \sqrt{x^4} = 16 \cdot x^2 = \boxed{16x^2}$
