Hint: use properties of logarithms.
 
What you apparently need to know yet, is some of the properties of logarithms.

For instance:

log(2 x 3) = log(2) + log(3)
2 x log(3) = log(32)

Are these familiar to you, or do you need to know more?

Very relevant equations: [itex]a log(b)= log(b^a)[/itex]. [itex]log(a)+ log(b)= log(ab)[/itex].
[itex]log(a)- log(b)= log(a/b)[/itex]
