First of all, we need all logarithms to have the same base. So, we use the formula
To change the second term as follows:
Finally, using the property
we have
So, the equation becomes
We can now use the formula
to write the equation as
Now consider both sides as exponents of 2:
This equation has no "nice" solution, so I guess the problem is as simplifies as it can be
