We had a quiz today and there was a problem where I didn't even know where to start... I was hoping someone could help me out on it.

I'm not very good with the syntax to this editor, but I'll try my best.

Evaluate the following integral:

∫ x^4 / (x^10 + 16) dx

Clarification:

Numerator: x^4

Denominator: x^10 + 16

(My problem was I didn't know if I should try substitution, because it doesn't look like I can factor the denominator.)

Thanks,

-Freyr.
