Don't know the steps in finding this derivative.
But the derivative is
Now simplify:
The answer is:
___ / 2 \ \/ x |(2 + log(x)) log(x)| x *|------------- - ------| | x 3/2 | \ x / ------------------------------- 4
___ / 3 \ \/ x | 2 (2 + log(x)) 3*log(x) 3*(2 + log(x))*log(x)| x *|- ---- + ------------- + -------- - ---------------------| | 5/2 3/2 5/2 2 | \ x x x x / ------------------------------------------------------------------ 8
