e^ln is an invalid expression - ln is not taking in any arguments.
4. Yes.
5. e^Ln(1) = 1
e^ln doesn't mean anything, you can't have a ln without a value of some kind
6. so
7. The question I was answering was:

ln | 3x - 1 | = 4

I took both sides to the power of e leaving:

e^ln|3x-1| = e^4

So I was wondering if e^ln = 1 times what ever is the power of e^ln?

You have to have the natural log of something. and are inverses and

so if f(x) = e^x, then

so, e^ln|3x-1| = |3x-1|
