Solve the Square Root Equation: √x = 12

To solve the equation $\sqrt{x} = 12$, we need to eliminate the square root by squaring both sides.

Let's follow these steps:

• Step 1: Square both sides of the equation to remove the square root:

$(\sqrt{x})^2 = 12^2$

• Step 2: Simplify the squared terms:

$x = 144$

Therefore, the value of $x$ that satisfies the equation is $\boxed{144}$.

Confirming with the choices given, the correct answer is 144, which matches choice 2.
