# Square Root Radical Sign [closed]

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?

• You can just use \surd. See How to look up a symbol or identify a math alphabet? – Werner Mar 26 '14 at 21:15
• Welcome to TeX.SE. Yes, just make sure you are in math mode: example $\sqrt{}$, or if you want the horizontal line $\sqrt{\hphantom{99}}$, where the widthof{99} determines how wide it is. If you actually have a number just use $\sqrt{<num>}$. – Peter Grill Mar 26 '14 at 21:19
• It's not clear what you're asking. Do you want a square root sign with nothing under it, or an nth root sign (like cube root, fourth root, etc.)? None of these require "advanced LaTeX" (first is \surd, second is \sqrt[n]{x}), so maybe you want something else? – wchargin Apr 17 '14 at 5:04

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

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


You can just use \sqrt{.........} and put what ever numbers between the brackets.

• Welcome to TeX.SX! You're missing the $ and $ for math mode. Also, it might be helpful to make a complete minimal working example so you can show the result in your answer. – Adam Liter Apr 17 '14 at 2:58
