Try this:
.EQ
up 30 1 ~ left "/" ~
{ down 30 { sum from { n ^ = ^ 0} to N
{ left [ N! over { (N-n)!n! } right ] } } right "" sup 2

Disclaimer: The 'left "/"' might be a something hacked into the version
of eqn I last looked at. The code is so bad looking that it is
difficult to determine. If it works, you have it.
The ~ move 1 em space while the ^ moves 1 en space. So if more room is
needed, add more ~. The right "" should solve the space problems with
the superscript. This is not a bug since all superscripts are designed
to be (by default) 4 point sizes smaller than the text point size. If
it doesn't work, add the size +2 again.
If this does not work, drop me an email note and we can arrange to talk
(I'm in NY).
