Solve the Square Root Equation: √x = 14

To solve this problem, we'll follow the steps below:

• Step 1: Start with the given equation: $\sqrt{x} = 14$.
• Step 2: Square both sides of the equation to eliminate the square root:

$(\sqrt{x})^2 = 14^2$

Step 3: Calculate the square of 14:
$14 \times 14 = 196$

Therefore, the value of $x$ is 196.

Comparing our solution with the provided choices, choice 3 ($196$) is the correct match.

Thus, the solution to the problem is $x = 196$.
