You are making the mistake of assuming that if
then
which is not right.
Rather than using brute force I suggest you try a few numbers that look like reasonable candidates. You want things to cancel out, and at first glance it would seem that trying values for x like x = 3, or x=2 may be promising. You can also try x = 1, since 1 raised to a power is always 1 and log of 1 is always 0. Post back with what you get.
