A: I have done it by consequatively differentiating until the seventh order and then evaluating at x = 0 to produce the desired series.

However I am at a loss as to how to do it by "expanding (1-4x)^1/2 and integrating term by term"..

...I know its basic stuff but I would much appreciate any help!
