Question

find the square root.
\sqrt{64} = \boxed{}

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 \( y^2 = 64 \).

Step2: Identify the number

We know that \( 8\times8 = 64 \) (or \( 8^2 = 64 \)) and also \( (-8)\times(-8)=64 \), but for the principal (non - negative) square root, we take the positive value. So \( \sqrt{64}=8 \).

Answer:

\( 8 \)
