Algebraic of a variable to itself

  1. Mar 14, 2007 #1
    I have been trying to solve algebraicly an equation of the following form for x with little success because x appears in the base and the exponent. Any help would be greatly appreciated.

    a/b=(x/c)^x

    A log approach only yields x*log(x/c)=log (a/b) which really doesn't get me anywhere.

    Well, you won't go very far! This is impossible to solve algebraically.

    Should be able to use the Lambert W function- it is defined as the inverse to the function xex.
