Question

Some Log help needed

Answer 1

What's the problem?

Answer 2

x+3 = ln(.9).
.2x = ln(t). Remember, the log in whatever base (in this case, e) will always negate the base that is raised to a power.

Answer 3

And vice versa as well.

Answer 4

wait you lost me

Answer 5

Where did I lose you? e^x is e to the power of x. If you want to get x just by itself - if x is in the power - then you can take the natural log (ln) of e^x, which gets rid of the e, just giving you x.

Answer 6

Got it got it

Answer 7

what about \[e \ln \sqrt{13}\]

Answer 8

So... What are you trying to do in this one?

Answer 9

Just evaluating the expression

Answer 10

Um. Take the ln of root 13, then multiply by e.

Answer 12

Got it

Answer 13

Cool cool.
