Follow AAEldar's exactly, but instead of v=x, use v=e^x.

All you need to know is that the derivative of e^x is itself.

Give it a try and tell us if you're stuck. Surely you will learn nothing by asking us to spoon feed you answers.

Im a bit confused on this part :S , so where does this come from?
multiplying by x/x is the same as multiplying by 1. ie it does not change the answer, only rearranges the terms. the purpose of this is to eliminate the fractions.

its like simplifing to try and remove the fraction from the question.

I am, just few questions I couldn't find answers to
I was referring to Spiral multiplying by x/x.

He in fact did nothing (since he multiplied by 1!).

However as a result, he was able to simplify the expression (doing something).

Hence by doing nothing, we do something.
