Consider using this log law:

a log b = log (b^a).

ln is just the same as log to the base e, it's just a simpler way of writing it, you should treat it just like any other log when using log laws.

what do the laws of logs say that xlogy is always equal to?
What can you do to combine two logs with the same base into 1?
