Hi, I was wondering if anyone can help me with the following integration problem.

I've provided part of my solution so far but its not the same as the answer given.

Question has been stated at the top of my solution and I am supposed to use Leibniz's rule to show that the I'(y) = 4y ln (2y).

I can't seem to get the answer so if anyone would be kind enough to point out my mistake, I'd be very grateful! thanks very much for your time

*Also in my solution a part of my first line of working has been cut off. There is supposed to be a limit of x = y^2 next to the ln (x + y^2) | [ if you know wot i mean :tongue2: ]
