Abstract

In this article we studied some growth properties of composite entire functions with finite iterated logarithmic order. Also, we defined iterated logarithmic order of an entire func-tion by using their maximum term. Further, we proved some results on the growth of composite entire functions of finite iterated logarithmic order in terms of their maximum terms.
