Question

How can I get a square root looking like these in LaTeX? Thanks!

Can you specify what aspects should be different to \sqrt{x}? — samcarter_is_at_topanswers.xyz, May 09 '17 at 20:09
I need the square root to look curly and bold like the one in the picture. I don't know what package I have to use, but inside the square root is also Times (New) Roman font. — Furfurr, May 09 '17 at 20:16
Maybe the answer could be updated. As the 'random guesses' by @samcarter show, no one really has a clear idea what you want. Maybe describe the look that you are rooting for (pun intended), or say what's bad about the standard $sqrt{x}$. — Narusan, May 09 '17 at 20:39
Please explain what you mean by "curly". To be honest, one doesn't come across this adjective very often when discussing the shape of square-root symbols. — Mico, May 09 '17 at 20:40
In case you mean that the corner of the root should be rounded, then mathptmx — samcarter_is_at_topanswers.xyz, May 09 '17 at 20:43
This square root is bolder than the classic LaTeX square root, it is shrinked and the corner is not that sharp, it's a bit curved. — Furfurr, May 09 '17 at 20:45
@Furfurr In case you don't want to wait until someone randomly guessed the correct font, you could go to http://www.tug.dk/FontCatalogue/mathfonts.html and try some fonts. — samcarter_is_at_topanswers.xyz, May 09 '17 at 20:56
Has the image that you have posted been produced with (some variant of) TeX, or by some other means? — GuM, May 09 '17 at 21:02

I guess you are looking for the services of the newtxmath math font package. Note that if you use it, you should probably also use the companion newtxtext text font package. Do check, though, if you want to (or are allowed to) use a Times Roman clone for your document.

\documentclass{article}
\usepackage{newtxtext,newtxmath}
\begin{document}
$\sqrt{x}$
\end{document}

I've already tried newpxmath, but it's still not curly enough. Thanks anyway. – Furfurr May 09 '17 at 20:30
@Furfurr - OK, I switched the answer to newtxmath. Any better? Maybe you should explain what you mean by "curly". – Mico May 09 '17 at 20:31
I’ve got the impression that $\sqrt{\mathstrut x}$ (with newtxmath) gets closer to the OP’s picture. – GuM May 09 '17 at 20:49

@GustavoMezzetti - Thanks. I wish I understood better what "curly" is supposed to mean in the context of square root symbols. – Mico May 09 '17 at 20:53

@GustavoMezzetti - Ah, I just noticed that the OP edited the query. I guess he/she means "curved" or "curvy" rather than "curly". – Mico May 09 '17 at 20:55

Yes, the bar of the root is rounded at the edge: I guess this means that the radical has not been produced by TeX’s “Rule 11”, which uses a horizontal rule… – GuM May 09 '17 at 20:59

A root sign with round corners:

\documentclass{article}
\usepackage{mathptmx}

\begin{document}

\begin{equation}
\sqrt{x}
\end{equation}

\end{document}

I vote this to be the curliest! – beldaz May 10 '17 at 04:49

If you want more vertical distance between the $x$ and the $\sqrt$ sign then try

\documentclass{article}


\begin{document}
    \[
    \sqrt{x\vphantom{^2}}
    \]
\end{document}

I don't need more space in the square root, I need the square root to look curly and bold like the one in the picture. I don't know what package I have to use, but inside the square root is also Times (New) Roman font. – Furfurr May 09 '17 at 20:15

I have used, for times, \usepackage[lite]{mtpro2} and \usepackage{letltxmacro}(do you want in this mode?).

\documentclass[border=1pt]{standalone}
\usepackage{letltxmacro}
\usepackage[lite]{mtpro2}
\makeatletter
\let\oldr@@t\r@@t
\def\r@@t#1#2{%
\setbox0=\hbox{$\oldr@@t#1{#2\,}$}\dimen0=\ht0
\advance\dimen0-0.2\ht0
\setbox2=\hbox{\vrule height\ht0 depth -\dimen0}%
{\box0\lower0.4pt\box2}}
\LetLtxMacro{\oldsqrt}{\sqrt}
\renewcommand*{\sqrt}[2][\ ]{\oldsqrt[#1]{#2} }
\makeatother



\begin{document}
$\sqrt{x} \quad \oldsqrt{x}$
\end{document}

Do you have a package that makes the square root curly? – Furfurr May 09 '17 at 20:35
For my opinion, there are package that makes the square root curly. Sorry. – Sebastiano May 10 '17 at 19:51
