In the expression
exponentiating and taking the log are inverses, so that
4x = 16
and
x = 4

You have to know how to read this.
The left side says:
e^[ some exponent ]
The exponent that is raised to reads as:
" I am an exponent ( natural log ) that gives you
when the base is "
-----------------------------
You do have this exponent with the base
on the left side, so the expression is
Then,
--------------------------------------
A simpler example of this would be:
What is ?
The left side says:
" I am raised to an exponent "
The exponent says:
" I am an exponent and if my base is ,
then I give you "
The base is , so the left side equals
