[Tex/LaTex] Square Root Radical Sign


Is it possible to type a radical of a square root equation as \sqrt{} with any number inside the bracket? I looked up how to do it but there were only these answers with advanced LaTeX that I don't understand. Any help someone?

\documentclass[preview,border=12pt,12pt,varwidth]{standalone}% change this line to \documentclass{article} or whatever you want.

The square root of 100 is $\sqrt{100}=10$. 
But the cubic root of 64 is $\sqrt[3]{64}=4$.
