Answer 3

@twodoggs I'm just extremely horrible at math... if i see a problem i can barely comprehend.. so those instructions don't even make sense to me ):

Answer 4

3ln 3 + 3ln c will become \[\ln3^3+\ln c^3\]

Answer 5

by the rules I posted ln simply means \[\log_{e} \]

Answer 6

are you with me?

Answer 7

\[3^3=27\]

Answer 8

so we get \[\ln27+\ln c^3 \]

Answer 9

which by the second rule logb(mn) = logb(m) + logb(n) becomes \[\ln (27c^3)\]

Answer 10

that should help you with the second 2

Answer 11

did any of that make sense?
