    FAO OP: It is easier on us if you can use LaTeX or even plain text, if used correctly. I noticed with another post that your image host does not seem too reliable or quick.

    NB: on your notation it looks like you're doing \bar{y} which means something completely different.

    In question 1 where has your denominator gone?

    Question 2 - check your signs when using negative exponents. \dfrac{d}{dz} -z^{-n} = nz^{-n-1} (either that or I cannot make out the + sign)

    Question 3 - Yep


    edit: you can also use wolfram to find out the answers to derivatives type in derive f(x) where f(x) is your function
