6N.13 e^ln

[Rachel Kwan 1B]

If you take e^ln of something, it cancels out as one and the exponent drops down right?

[Savana Maxfield 3F]

Yep!

[Andreas Krumbein 1L]

Yup, e^ln(anything) =anything, and conversely, ln(e^{anything else})=anything else.

[Rachael Cohen 3G]

Yep! So if you have something like ln(a)=b:
ln(a) = b
e^(ln(a)) = e^b
a=e^b

just remember to put e on both sides!
