The problem asks us to solve the equation $x^2 = 4$ using the square root property. We need to simplify the answer and provide an exact answer, using radicals and $i$ if needed. We are also instructed to use a comma to separate answers if there are multiple solutions.

1. Problem Description

The problem asks us to solve the equation $x^2 = 4$ using the square root property. We need to simplify the answer and provide an exact answer, using radicals and $i$ if needed. We are also instructed to use a comma to separate answers if there are multiple solutions.

2. Solution Steps

To solve the equation $x^2 = 4$ using the square root property, we take the square root of both sides:

$\sqrt{x^2} = \sqrt{4}$

This gives us:

$x = \pm \sqrt{4}$

Since $\sqrt{4} = 2$, we have:

$x = \pm 2$

Therefore, the solutions are $x = 2$ and $x = -2$.

3. Final Answer

2, -2
