Answer 3

To solve the equation $x^2 = 784$, we need to find the values of $x$ that satisfy the equation.

Taking the square root of both sides, we get:

$\sqrt{x^2} = \sqrt{784}$

Remember that the square root of a number is positive, so we have:

$|x| = 28$

To remove the absolute value, we consider two cases:

Case 1: $x = 28$

Case 2: $x = -28$

So the solutions to the equation are $x = 28$ and $x = -28$.
