We are asked to evaluate the expression $\sqrt{(-7)^2}$.

1. Problem Description

We are asked to evaluate the expression $\sqrt{(-7)^2}$.

2. Solution Steps

First, we evaluate $(-7)^2$.

$(-7)^2 = (-7) \times (-7) = 49$

Now, we need to find the square root of

4

9. $\sqrt{49} = 7$

Alternatively, we can use the following property:

$\sqrt{x^2} = |x|$

In this case, $x = -7$.

$\sqrt{(-7)^2} = |-7| = 7$

3. Final Answer

7
