Question

find all real square roots of 25. 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 \( y^2 = x \). For \( x = 25 \), we need to find all real \( y \) where \( y^2 = 25 \).

Step2: Solve the equation \( y^2 = 25 \)

Taking square roots on both sides, we get \( y=\pm\sqrt{25} \). Since \( \sqrt{25} = 5 \), then \( y = 5 \) or \( y=- 5 \) because \( 5^2=25 \) and \( (-5)^2 = 25 \).

Answer:

-5, 5
