**f(x)= x^(2/3) (6-x)^(1/3)**

I have found the first derivative and checked my solution:

′()= 4− / ^(1/3) (6−)^(2/3)

′()= 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!
