Evaluate the definite integral.
dx/(x*sqrt(lnx)) from 1 to e^4
I'm having trouble figuring this out, I might be overthinking it. The way I've approached this is by using u substitution and letting u=lnx. I keep getting the wrong answer though.
Help is appreciated!!

Calculus 
Reiny,
For the integral I go
2 (ln(x))^(1/2) or 2√( ln(x) )
Got it by playing around with it
I will let you do the substitutions.
