Remark on: “Exp-function method for the exact solutions of fifth order KdV equation and modified Burgers equation” [Appl. Math. Comput. (2009) doi:10.1016/j.amc.2009.07.009]

By means of the Exp-function method, Inan and Ugurlu [Appl. Math. Comput. (2009) http://dx.doi.org/10.1016/j.amc.2009.07.009] reported eight expressions for being solutions to the two equations studied. In fact, all of them can be easily simplified to constants.
