Pick a convenient number for x. Let's use 16.
Since the square root of 16 is 4, the left side of the equation simplifies to 3.
So the equation becomes 3=16^w and we need to solve for w.
We can estimate that w will be somewhere between 1/4 and 1/2.
None of the answers fall into that range.
Are you certain that the problem is correctly stated?
