I used to be able to do logorithims a long while ago, but now I forgot how to. I think I got the hang of it now, but I just want to make sure.

ln x = 3 ( you divide by 3 since 3 is multiplied with ln x)
x = e^3

ln x^3 = 9
e^9 = x^3
e^3 = x

3 ln x = 9
(3 ln x)/ 3 = 9/3
ln x = 3
x = e^3

if 3 ln x = 9, divide by 3 and get ln x = 3
then undo ln with exponentiation:
e^(ln x) = e^3
x = e^3

No.
3 ln x = 9
lnx=9/3
lnx=3
x=e^3

3 ln x = 9
ln x = 3
x = INV ln 3 (on calculator)
x = 20.1 (to 1 dec. place)
