Question

Differentiate y=e^x/x^2

Answer 1

y'= ((xe^x) - (2e^x)) / x^3

Answer 2

i got
\[[(xe ^{x})(x+2)]/x ^{4}\]

Answer 3

y' = [x^2(e^x) - e^x(2x)]/x^4
=[(e^x)(x^2-2x)]/x^4
=[x(e^x)(x-2)]/x^4
=[e^x(x-2)]/x^3

Answer 4

oh yea...you can cross out one of the x's and yea you should get what lgsallote got
