Homework Statement
I am trying to integrate the PLanck function to get the Stefan Boltzmann law. After factoring out constants, and substituting x = hv/kT I am left with the following integral:
B(T) = ∫ x3/(ex - 1) dx integrated from 0 to ∞
The next step in my notes is that the result of this integral is ∏4/15 and I have no idea how this is done!

The Attempt at a Solution
I tried Wolfram with this and it gave such a complicated answer that I was even more confused - certainly it looked nothing like the one in the notes! I know asking for help shouldn't be my first resort, but have no idea how to begin tackling this I'm afraid.
