Don't know the steps in finding this derivative.
But the derivative is
The answer is:
1 ------ log(x) / 1 log(log(log(x)))\ (log(log(x))) *|--------------------- - ----------------| | 2 2 | \x*log (x)*log(log(x)) x*log (x) /
/ 2 \ 1 | / 1 \ | ------ | |- ----------- + log(log(log(x)))| | log(x) | 1 \ log(log(x)) / 1 3 2*log(log(log(x))) | (log(log(x))) *|- ----------- + ----------------------------------- - ------------------- - ------------------ + ------------------ + log(log(log(x)))| | log(log(x)) 2 2 log(x)*log(log(x)) log(x) | \ log (x) log(x)*log (log(x)) / ------------------------------------------------------------------------------------------------------------------------------------------------------------ 2 2 x *log (x)
