Question

Find the square root of $x^2$.

Answer 1

Find the square root of given expression

The square root of any number is equal to a number, which when squared gives the original number. Let us assume that $m$is a positive integer, such that $\sqrt{m.m}=\sqrt{m^2}=m$

Given expression, $x^2$

So, $\sqrt{x^2}=x$, but that's only true for $x^2\ge 0$

Hence, the square root of $x^2$ is $x$ for $x\ge 0$.
