Evaluate the definite integral.

Question

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!!

Answer 1

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.
