Question

current skill $ what are the square roots of 4?

Explanation:

Step1: Recall square root definition

A square root of a number \( x \) is a number \( y \) such that \( y^2 = x \). For \( x = 4 \), we need to find \( y \) where \( y^2 = 4 \).

Step2: Solve for \( y \)

We know that \( 2^2 = 4 \) and \( (-2)^2 = (-2)\times(-2)= 4 \). So the square roots of 4 are 2 and -2.

Answer:

The square roots of 4 are \( 2 \) and \( -2 \) (or \( \pm 2 \)).
