    Just forget it.
    You can't express the solution of that equation in an "ordinary" manner.
    Probably, it is a typo.

    Well..
    x^x = 58
    If you do trial-and-error on your calculator... you get something like x = 3.35475 (Approximation)
    Then again, I have no idea why you would get such a problem.. we never even got this far in Algebra 2. :)
