Hint: use properties of logarithms.

 

[I like Serena]

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: a log(b)= log(b^a). log(a)+ log(b)= log(ab).
log(a)- log(b)= log(a/b)
