Question

ln 1/e^3

I got -1 but Im not sure if that is correct?

Answer 1

almost, I think you are on the right track though... let me work it out first... :)

Answer 2

okay

Answer 3

alright, so first convert 1/e^3 to negative exponents, what did you get (or does that even make sense :) )?

Answer 4

thats where I got the -1, bc if its a fraction it has to come from a neg number right?

Answer 5

or wait, that exponent might be different that thinking...

Answer 6

-3

Answer 7

Charlie how did you get the answer?

Answer 8

ln(e^-3), ln and e cancels each other

Answer 9

is the question this or this?

\[\ln(\frac{1}{e^3})\]

\[[\ln(1/e)]^3\]

Answer 10

right, I think charlie's got it :)

Answer 11

the first

Answer 12

ok, then yes, the conversion should be e^-3 because not only is it a fraction (-1) but it is also to the third power (3) so combining gives you -3

Answer 13

so when I write it out I can write it like this?

Answer 14

Yes, both ways
