1. The problem statement, all variables and given/known data Find the second derivative of the function: f(x)= x^(2/3) (6-x)^(1/3) 2. Relevant equations The chain, product and quotient rules 3. The attempt at a solution I have found the first derivative and checked my solution: ′()= 4− / ^(1/3) (6−)^(2/3) The final solution is supposed to be: ''()= -8 / ^(4/3) (6−)^(5/3) I know almost all the steps but I couldn't reach the final answer! Can you please help me? Thanks in advance!
