In this paper we complete the solution to the equation w + x+ y = z  , where w  , x  , y  , and z  are positive integers and wxyz  has the form 2r3s5t  , with r  , s  , and t  non negative integers. Here we consider the case 1< w < x< y  , the remaining case having been dealt with in our paper: On the Diophantine equation 1 +X + Y = Z  , Rocky Mountain J. of Math. This work extends earlier work of the authors in the field of exponential Diophantine equations.
