Summary We consider entire functions of the form f = Sigma a(i)e(gi), where a(i)(not equivalent to 0), g(i) are entire functions and the orders of all ai are less than one. If all the zeros of f are real, then f = e(g) Sigma a(i)e(hi), where h(i) are linear functions. Using this result, we can prove that f = a(i)e(g) if all zeros of f are positive, which also generalizes a result obtained by A. Eremenko and L. A. Rubel.
