Question

multiple-choice question what does \\(\sqrt{64} =\\) \\(\square\\) 4 \\(\square\\) 8 rewatch

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 \( x = 64 \)

We need to find \( y \) where \( y^2 = 64 \). Check \( 8^2 = 8\times8 = 64 \), and \( 4^2 = 4\times4 = 16
eq64 \). So \( \sqrt{64}=8 \).

Answer:

8 (the option with "8" should be selected, i.e., the second checkbox option labeled "8")
