Explanation:

Step1: Recall the definition of square root

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

Step2: Find a number whose square is 64

We need to find \( y \) where \( y^2 = 64 \). We know that \( 8\times8 = 64 \) (or \( 8^2 = 64 \)) and also \( (-8)\times(-8)=64 \), but for the principal (non - negative) square root (which is what is typically referred to when we use the square root symbol \( \sqrt{} \) without a negative sign), we take the non - negative value. So \( \sqrt{64}=8 \).

Answer:

8
