Real Quick Calculus Help

[RsProd]

Hey guys, just looking for confirmation that my answers are correct.
Year 13 Calculus, not sure what grade that is in America etc.
Anyways, here's the questions, Under the topic:

Advanced Polynomial Differentiation:

1) x^1/2(x^3-5)
2) (1) / (2x + 13)^5
3) (7) / 3(x + 1)^10

If you have the time to explain how to do those, It'd be much appreciated.
If you don't feel like posting here, [email protected] is my MSN.

Thanks a lot

One second, I'm solving.

1) simplifies to x^(3/2)-5x^1/2, derives to 3/2 x^(1/2) -5/2 x^(-1/2)

2) same as (2x+13)^-5, derives to -5(2x+13)^-6 *(2) (chain rule)

3) similar to 2, becomes -70/3 (x+1)^-11

I will help you with these, and can explain how it is done as well.

Just contact me on MSN - If I remember correctly you still have me added?
