No instructions were included; I'll guess that you're supposed to solve the logarithmic equation.

The first step will be combine the logs on the left-hand side into one term, using log rules.

. . . . .

Then equate the arguments, and solve the resulting rational equation.

. . . . .

. . . . .

...and so forth. :wink:
