For 17b why isnt it x to the power of (-2n-1)/2?

i think they meant to write -(2n+1)/2 but they made a typo

whilst some are unrealistic, you have no control as to what you'd be given in a test. No matter how tedious some of the questions might be, it'd likely be great to build intuition.

induction is always a good option if you're confused, that way u can check if the formula u guessed is correct

True, and differentiation induction is one way to present something a bit different, and possibly in a form that wasn't anticipated (like with factorials, here).
