I'm having some trouble with a couple HW questions. A little help would be greatly appreciated.

1. Find the derivative of:

y=2(arcsin(x^2))

I thought you had to make a u-substition of u=x^2, but it doesnt seem to work out. If anyone could point me in the right direction that would be good.

2. Find the derivative of: y=ln(x^7(x+5)^9((x^2)+9)^2)

For this I took the ln of both sides, then tried using the chain rule over and over, but again i didnt get the answer.

If anyone could guide me in the right direction I would be really

Thanks
