## Homework Statement

[1] integral of e^(-ln(x))

[2] integral of 2/(sqrt(x)) * e^(sqrt(x)))

## Homework Equations

## The Attempt at a Solution

Is [1] 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 [2], 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
