Hey all
Im working on a math problem:
e^(-z/d) = 1/10
my steps are:
1. Add ln to both sides
ln(e^(-z/d) = (ln 1) - (ln 10)
From here, I understand that on the right i get (-ln 10)
and i have been told that on the left of the = i can reduce to (-z/d)
Then i can reduce to:
(z/d) = ln 10
I think i may just be having a brain fart, but i cannot see how to bring down (-z/d)
and be able to put it in front of ln(e) (which i know = 1)
Anyway, im sure this is some simply algebra i forgot, so sorry if this is dumb!
