ABSTRACT: Digital
roots of numbers have several interesting properties, most of which are
well-known. In this paper, our goal is to prove some lesser known results
concerning the digital roots of powers of numbers in an arithmetic progression.
We will also state some theorems concerning the digital roots of Fermat numbers
and star numbers. We will conclude our paper by an interesting application.
