Question: Strange integration output

Hello, I'm trying to integrate (for a homework) the Planck radiation formula. But the result (see the Maple10 worksheet below) is so strange (polylog(4,exp...) stuff) that I can't figure out what it means. I tried to compute taylor series at T=0 (because the exercise is to prove that integral is proportional to T^4) but Maple can't do it.
