[OS X TeX] Changing the size of pp=th roots?

[Luis Fernando Sequeira]

As Michael said, the root index is in scriptscripystyle but you can force it to be
larger, eg

 $\sqrt[\scriptstile{p}]{n}$

and you can raise it too - something like 


  $\sqrt[\raisebox{0.25ex}{$\scriptstyle{p}$}]{n}$

The trouble with this is that once you start doing these things like \raisebox you leave the nice abstraction of concentrating on content and have to worry about form. Different radicands will yield different sizes and cause difference adjustments. But still you can explore that. 
For sure using \scriptstyle is fine, and you can easily abstract that away by defining a new command:

\newcommand{\ssqrt}[2][]{\sqrt[\scriptstyle{#1}]{#2}}
