I came across this exercise and I don't know what to do next (or if I solved it correctly to this point)

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.
