Question

Write the expression as a single natural logarithm.
3ln3 + 3lnc

A. ln(27 + c3)

B. ln9c3

C. ln27c

D. ln27c3

Answer 1

Use this rule of logarithms to deal with the 3's in front.
\[\huge a*\log(b)=\log(b^a)\]

Then use this rule to combine your logs.
\[\huge \log(b)+\log(c)=\log(b*c)\]

Answer 2

@zepdrix i believe its B am i correct

Answer 3

Mmmmm no.

Answer 4

After you apply the first rule of logs, you should end up with a 3^3 term. Which is 27.
