can someone sow me step by step how to evaluate the integral of the square root of x^3 using a u substitution? I don't understand this topic and I have a lot of problems to do like this so can someone just sow me so I can see the process? Thanks.

You want the
integral [ √(x^3)] dx ?
= integral [x^(3/2)] dx
= (2/5)x^(5/2) + c
Why would you want to use substitution for one that simple?
