(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

I need to use a substitution technique and then the table of integration to integrate the following:

∫ x^{5}√(x^{4}– 4) dx

and i am given a hint which is x^{5}= (x^{3})(x^{2})

I would assume that

u = x^{4}– 4, then du = 4x^{3}

and that at some point a^{2}= 4 and a = 2

However, the x^{5}= (x^{3})(x^{2}) is confusing the heck out of me. Need help!

1. The problem statement, all variables and given/known data

2. Relevant equations

3. The attempt at a solution
