Hi,
Is there somebody who can give the solution for the integral of :
1/ln(x^x) where ln is the natural logaritme?
Thanks for a response

Write ln(x^x) = x*ln(x). Now you have int{ dx/x * 1/ln(x)}. Do you
recognize dx/x?

ln(ln(x))

Whys did you give him the answer? Would it not be better to just
supply a hint and let the OP work it out for himself?

He asked for a solution ("Is there somebody who can give the
solution...") and not a hint.
Hence my answer.
Sorry.
