Question

How do you simplify `lne^4`?

Answer 1

`4`

Explanation:

You may put any power in the argument before the `ln`:
`lne^4=4lne` (this goes for `log`'s to any base)

Then since `e` is the base of the `ln`-function (`lnx=log_e x`), it follows that: `lne=log_e e=1`, just as `log_10 10=1`

So: `lne^4=4*lne=4*1=4`
