I have, as part of an equation, the object

a^{5} \left(\frac{b}{c}\right)^{\frac{2}{3}}

The problem is that the 2 and 3 are very small (compared to the 5) and I would like all sub/superscripts to be the same size just as all body text is the same size. Is there a way of defining the font size inside the equation environment?

Have you tried dfrac in place of frac? – 56phil Sep 5 '12 at 16:42
I suggest writing ^{2/3} or stick to \frac. – egreg Sep 5 '12 at 17:36

I've managed to solve it by replacing \frac by \tfrac.

Try dfrac instead of frac: a^{5} \left(\dfrac{b}{c}\right)^{\dfrac{2}{3}} You will need the amsmath package

But then the 2 and 3 are larger than the 5! – Hendrik Vogt Sep 5 '12 at 16:50
I did not realize that. TY. – mythealias Sep 5 '12 at 17:04
