Use the chain rule to find derivatives in each of the following and please show steps: Each  problem is set up in parenthesis.  

(a) f(x) = (3x^2 + 2)^4                (b) f(x) = (3x^1/3 + 2x^1/2)^-3   

(c)  f(x) = (2x^3 + x^2 over 3x)^1/2  (this problem is set up as a fraction and squared 1/2 outside of the parentesis.
