Hey There,

I am doing a question and I can solve it the antiderivative way, but I can't seem to come up with the substitution method.

3 + x^3/2 dx

__ _____ divide by

x^3 3

So I put the integral sign 3x^-3 - 3x^3/2 dx

now do I take out a 3 and have 3(x^-3-3x^3/2) dx or NO??

I can't figure out the U and du.

Any help would be great, thanks.
