I don't believe either of those is meant to be done by u-substitution. Please show us the entire problem including instructions, and tell us where it came from.

Actually, though I don't think it's your basic u-substitution problem, I notice that if you let u equal one of the radicals, something interesting will happen, which may lead to something useful in solving the definite integral. I haven't tried it to see if I'm right, but give it a try.
And, again, showing us the context might help.
