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:

Where:

and

(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:

You get:

To verify:

And there you go.
