Inverse Functions

As a relatively inexperienced user of Mathematica, could someone inform me
how to get a closed-form expression--in terms of elementary functions if
possible--for the inverse of the function

                           f(x) = x^x

Since the function is one-to-one over its domain, it does have a
mathematical inverse.

Thank You,

Julian P. Charko, P. Eng.
