Given a root symbol that becomes tall:


The N is now rendered disproportionately small.

Does a fix exist? Is this a bug?

edit: as a follow-up to the accepted answer, here is a reference on font size and style setting

You could try

text{\sqrt[\large N]{\dfrac{\lambda}{3^e}}: $\quad\displaystyle\sqrt[\large N]{\dfrac{\lambda}{3^e}}$

or text{\sqrt[\Large N]{\dfrac{\lambda}{3^e}}: $\quad\displaystyle\sqrt[\Large N]{\dfrac{\lambda}{3^e}}$

but \sqrt[\huge N]{\dfrac{\lambda}{3^e}}: $\quad\displaystyle\sqrt[\huge N]{\dfrac{\lambda}{3^e}}$

starts to look very odd.


I was looking at the larger indices and they looked kind of crowded to the radical. I think these look even better:

text{\sqrt[\raise{2pt}{\large N}]{\dfrac{\lambda}{3^e}}: $\quad\displaystyle\sqrt[\raise{2pt}{\large N}]{\dfrac{\lambda}{3^e}}\quad\Large\star$

or text{\sqrt[\raise{2pt}{\Large N}]{\dfrac{\lambda}{3^e}}: $\quad\displaystyle\sqrt[\raise{2pt}{\Large N}]{\dfrac{\lambda}{3^e}}$

I think the starred one looks best

  • $\begingroup$ @NewAlexandria: I'm sorry, I should have mentioned that... I just assumed people knew how to see the source. Thanks for mentioning that! $\endgroup$ – robjohn Oct 8 '12 at 16:40
