a. the square roots of 25 are . (use a comma to separate answers as needed.)
b. the square roots are not real numbers.

Explanation:

Step1: Recall square root definition

A square root of a number \( x \) is a number \( y \) such that \( y^2 = x \). For \( x = 25 \), we need to find \( y \) where \( y^2 = 25 \).

Step2: Solve for y

We know that \( 5^2 = 25 \) and \( (-5)^2 = 25 \) (since the square of a negative number is positive). So the square roots of 25 are 5 and -5.

Answer:

A. The square roots of 25 are \( 5, -5 \).
