How to give the exponent terms in the denominator part of a \frac expression more vertical space?
I think the denominator of your \frac
expression suffers from two issues:
- a "cramped" look, i.e., the exponents are not raised much above the baseline
- first- and second-order exponents are raised to (very nearly) the same height
How to remedy these issues?
To address the first issue, switch to "uncramped" mode -- see the
\ufrac
macro below.To remedy the second issue, I suggest you switch from
{n^n}^2
ton^{n^2}
. (The two forms are the same, mathematically speaking, but they are quite differnt from a typographic point of view.) That, or use parentheses to visually "enclose" then^n
term.Alternatively, consider switching from "standard"
\frac
notation to inline-fraction notation.
Whatever else you do, please don't use the unnecessary *
multiplication symbol. If you can't do without an explicit multiplication symbol, do use \cdot
, not *
.

Does this go in the right direction?
