Jonathan Sondow, Diego Marques, Algebraic and transcendental solutions of some exponential equations, Annales Mathematicae et Informaticae 37 (2010) 151-164. FORMULA x0 = -((x*ProductLog(-1, -(log(x)/x)))/log(x)), with x = 3/2, where ProductLog is the Lambert W function. EXAMPLE x0 = 7.408764686965774521957295028510614389804171141074... z = x0^(3/2) = 20.16595073003535058942970947434890012034363496 ... z > e^e = 15.15426224... = A073226.
