Question

find the square root.
\sqrt{49} = \square

Explanation:

Step1: Recall square root definition

The square root of a number \( x \) is a value \( y \) such that \( y^2 = x \). We need to find \( y \) where \( y^2 = 49 \).

Step2: Find the number whose square is 49

We know that \( 7 \times 7 = 49 \) (or \( 7^2 = 49 \)) and also \( (-7)^2 = 49 \), but for the principal (non - negative) square root, we take the positive value. So \( \sqrt{49}=7 \).

Answer:

\( 7 \)
