Question

find the square root.
\sqrt{121} = \square

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: Find \( y \) for \( x = 121 \)

We need to find \( y \) where \( y^2 = 121 \). We know that \( 11 \times 11 = 121 \) (or \( 11^2 = 121 \)). So, \( \sqrt{121}=11 \).

Answer:

11
