Something is wrong with your question. There is no variable, so nothing to solve. The larger problem is that your equation essentially states that #3^-1=81#, which is clearly incorrect.

Solve the following? #log_3 81=-1#.

That's not really a question. You are missing information. Is there another equation? Are you to simply put it into slope-intercept form? The problem is that you have one equation with two variables. Doesn't work, as there are literally infinite solutions.
