How do I find the second derivative of the function:
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)
The final solution is supposed to be:
''()= -8 / ^(4/3) (6−)^(5/3)
I know almost all the steps but I couldn't...

Homework Statement
Use Buckingham's Pi Theorem to describe waves amplitude.
The Attempt at a Solution
Waves amplitude depends on:
Geometric variables: L,A
Kinematic variables: g,c (c = waves speed)
Dynamic variables: roh (density), sigma (surface tension)
Using MLT:
L = L, A =...
