Well, we are given:
Well, let's deal with the right side first, they are currently in different bases, therefore we must change the bases by using the change of base formula:
Where we are using base 10 because the right side has a base 10 logarithm.
Therefore we get:
(They are very close together, where the first difference is in the ten thousandths place.)
So we get:
There's really not an easy way to solve this, so I'm going to make the following approximation:
And there you go.
