Hint: If they'd given you the equation "8x = 16", what would have been your first step?

If you mean "divide 16 and 8 by 8 to get 'log(x) = 2'", then yes, that is how one would start the solution process.

Now convert the logarthmic equation to its equivalent exponential form, and complete the solution. (Since you didn't mention what the base of this "Log" is, I can't offer specific advice.)
