Homework Statement
I need to find the derivative of V(u) with respect to x
V(u)=((a-pX)/q)^B
Homework Equations
f(x)=aX^b ==> f'(x)=baX^b-1
The Attempt at a Solution
I wanted to distribute the B throughout and then I would have got -BpX^B-1, but I know this isn't doable. What I really need to know is how to deal with the entire function raised to a power. Once I get the function by itself (not raised to power B) I can get through it. Thanks for your help!
