..need help with 2 questions.
e^(3s) = r Mr F says: Therefore 3s = ln (r). What you have below is wrong.
would it be 3s = r ? would i take the log of each side? since it equals (r) and not a number i can't get (s) byself?
i just did log7t = g Mr F says: Therefore 7t = 10^g. What you have below is wrong.
and what i did with that one was 7t =10g but since there is not base or exponent?? not sure if that is the right answer.
since there is no exponet would it be zero? how can i log both sides?
then i divided the 10/7 getting (t) by itself. which gave me 1/7 = t ??
can anyone help??
