So this is my (simple) problem, I would like to have the superscript (number 2) in a better position compared to the first case which looks really awful to me. A first solution was to add the parentheses but it seems too bad in a long equation to have much of them.
\documentclass{article}
\usepackage{amsmath}
\usepackage[utf8]{inputenc}
\begin{document}
\begin{align}
\dot{\theta}_{M}^{2} && (\dot{\theta}_{M})^{2}
\end{align}
\end{document}
\dot\theta_M{}^2
look better to you? – Sergei Golovan Dec 29 '17 at 9:12\dot\theta_M^{\,\,2}
