Ah I just had Discrete Math last Winter and I don't even remember how to do this stuff. I sold my book and I do not have my notes.

I think you can start about by breaking it into two pieces:

for i = 1 to n sigma(i^2) * sigma(3^i)

Then there should be some general rule for what to do with sigma(i^x) and sigma(x^i)... giving you a couple formulas to multiply. And that is what I would look up in my text book if I had it.

Damn this is probably why I barely got a B- in the class.
