question
express in simplest radical form.
\sqrt{49}
answer attempt 1 out of 5

Explanation:

Step1: Recall square root definition

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

Step2: Identify the square of 7

We know that \( 7 \times 7 = 7^2 = 49 \). So, by the definition of square root, \( \sqrt{49} = 7 \).

Answer:

\( 7 \)
