[texhax] inline form of an equation

[William Adams]

Okay, I have:

\documentclass{article}
\usepackage{amsmath}
\usepackage{mathptmx}
\begin{document}
$\sqrt{\frac{\sum d^2}{2n}}$
\end{document}

Would it be okay to do:

\documentclass{article}
\usepackage{amsmath}
\usepackage{mathptmx}
\begin{document}
$\sqrt{{\sum d^2}/{2n}}$
\end{document}

William
