Homework Statement
Find f'(x): [itex] (abs(((x^2)*((3x+2) ^(1/3)))/((2x-3)^3)) [/itex] <- Not sure why it''s not showing up but the 1/3 is an exponent to just the (3x+2).
Homework Equations
Product Rule and Quotient Rule for Differentiating
The Attempt at a Solution
So I thought I should split it into two parts: A and B.
A) [itex] (x^2)/((2x-3)^2) [/itex]
B) [itex] ((3x+2)^1/3)/(2x-3) [/itex]
My plan was to differentiate each part and then multiply them together, since multiplying their denominators together gives me the original denominator power (4).
I end up getting for A) (-12x^2 + 18x)/((2x-3)^4)
For B, I have something which seems much more complex, because of the negative fractional exponents, and this is where I'm stuck. I want to simplify, but I'm not sure how to without screwing everything up. This is my last step for B:
[itex] ((3x+2)^(-2/3)*(2x-3) - 4(x-3)*((3x+2)^(1/3)))/((2x-3)^2) [/itex] <- The -2/3 is the exponent
I really appreciate the help. And also, as for the absolute value part of the question, well I haven't even thought about that- I'm stuck on the easy part itself. -_-
Thank you!
