Question

What is `log_e` of e?

Answer 1

`log_ee=lne=1`
(`ln` is a button on you GC, equivalent to `log_ee`)

By definition the `log_aa=1`, whatever `a` is.
(as long as `a!=0` and `a!=1`)

What `log_ax` means is:
What exponent do I use on `a` to get `x`?

Example: `log_10 1000 = 3` because `10^3=1000`

So `log_10 10 = 1` because `10^1=10`
And this goes for any `a` in `log_aa` because `a^1=a`

Answer 2

The Answer is 1.

`ln(e)` is the same thing as `log_e(e)`

Because `e^1 = e, log_e(e) = 1`
