Explanation:

Step1: Recall square root definition

The square root of a number \( x \), denoted \( \sqrt{x} \), is a value \( y \) such that \( y^2 = x \).

Step2: Calculate \( \sqrt{4} \)

We need to find \( y \) where \( y^2 = 4 \). We know that \( 2^2 = 4 \) (since \( 2\times2 = 4 \)), so \( \sqrt{4}=2 \).

Answer:

\( 2 \)
