Question

Derivative answer form question.

Answer 1

\[J(v)=(v ^{3}-2v)(v ^{-4}+v ^{-2})\]
I solved it and got
\[6v ^{-4}+v ^{-2}+1\]

Answer 2

Can i leave it in this form or do i have to solve it using:
\[\frac{ 1 }{v ^{4} }\] and the like

Answer 3

it is fine the way it is, unless you have multiple choice and have to tweak it to match one of the choices

Answer 4

I see. thank you~ my book only gives the positive exponent form, i was worried this was wrong.
