How to write pow math?
Embrace the {w^{\mathrm{anterior}}}
rather than the {i^{w}}
. Also, \mathrm
for math-sized text (by "text", I mean phonetic language, not a collection of math symbols).
\documentclass{article}
\begin{document}
$i^{w^{\mathrm{anterior}}}$
\end{document}
If I understood you correctly, you want the superscripts have normalsize
plus an sf
shape, you can use \mbox
.
\documentclass[12pt,a4paper]{article}
\begin{document}
\newcommand{\mb}[1]{\mbox{\sffamily#1\,}}
$\mb{i}^{\mb{w}^{\mb{anterior}}}$
\end{document}
Another good approach is \operatorname{anterior}
from amsmath
, especially if you want two of these variables to appear consecutively.
Personally, I would prefer to define \newcommand\anterior{\operatorname{anterior}}
, analogously to \sin
or \log
.
