Math Help - Couple of Integrations

1. Couple of Integrations

I have two seemingly similar problems,but unfortunately I'm having a hard time solving them. I hope somebody here can solve this for me... or maybe just a rough solution will do.

1.) What is the integral of x[(x^3 + 4)^(1/4)] ?

2.) What is the integral of (x^4 - 4)^(1/3) ?

Thanks!

2. Re: Solving definite integral thread 2?

Do you have a reason to think that the integrals can be written in elementary form?
