For part a) I have got the nth derivative as being n!/((1-x)^(n+1)), but for the second part have got nothing close to that, which means I must be wrong, but I can't see why. Help please?

Something went wrong while you were applying the Leibniz formula? The graphs of \dfrac{1}{1 - x} and \dfrac{x}{1 - x} are mere translations of each other across the y-axis as \dfrac{x}{1 - x} = \dfrac{1}{1 - x} - 1, so the two should actually have the same derivatives.

Or perhaps you should put (-1)^n at the front of your expression?

Would you be able to let me know what you got for the nth derivative? But thank you!
