## The Attempt at a Solution

My teacher has said that these questions should be like other basic antiderivative questions, but they seem to be stumping me, probably because of the fractions involved. In short I have no idea where to start with these questions, even though (supposedly) the answers are not that hard to find. If anyone can get me started on the right path for these questions here it would be greatly appreciated, thanks in advance.
