integral of e^(-ln(x))
 integral of 2/(sqrt(x)) * e^(sqrt(x)))
The Attempt at a Solution
Is  the same as writing 1/e^lnx?
In general, example of 1 and 2, we treat the negative of an expo power, e^-x as 1/e^x right?
So for , u = sqrt(x) (from the e), should be written as -sqrt(x)?
I thought in regular integration:
x^2 / x^3 , where u is x^3, and it is not equivalent as -x^3, or x^-3
