    thanks
    Consider:

    The inverse of the function w = z\, e^z requires using a special function called the Lambert W-function: w^{-1}(z) = W(z).

    What you want is even more complicated .....

    Why do you want the inverse, anyway? Note: If you have to find the derivative of the inverse function for a particular value of z, this can be done without using an explicit rule for the inverse ......

    Maybe this function does not even have an inverse? Does it?
