this is very basic stuff ... where are you having problems?

Well, I find derivatives very easy, it's just that I am having trouble with finding the antiderivatives

antiderivative of $\displaystyle x^n$ is $\displaystyle \frac{1}{n+1} \cdot x^{n+1}$

for $\displaystyle \int_4^9 \sqrt{x} \, dx$ , $\displaystyle n = \frac{1}{2}$

give it a go ...
