Question

find all real square roots of 9. if there is more than one answer, separate them with commas. if there are none, click on
one\.

Explanation:

Step1: Recall square root definition

A real square root of a number \( x \) is a number \( y \) such that \( y^2 = x \).

Step2: Solve for \( y \) when \( x = 9 \)

We need to find all real numbers \( y \) where \( y^2 = 9 \). Solving this equation, we get \( y=\sqrt{9} \) or \( y = -\sqrt{9} \). Since \( \sqrt{9}=3 \) and \( -\sqrt{9}=-3 \), the real square roots of 9 are 3 and -3.

Answer:

3, -3
