ON THE LAST DIGIT AND THE LAST NON-ZERO DIGIT OF nn IN BASE b
Grau, Jose Maria; Oller-Marcen, Antonio M.;

Abstract
In this paper we study the sequences defined by the last and the last non-zero digits of $\small{n^n}$ in base b. For the sequence given by the last digits of $\small{n^n}$ in base b, we prove its periodicity using different techniques than those used by W. Sierpinski and R. Hampel. In the case of the sequence given by the last non-zero digits of $\small{n^n}$ in base b (which had been studied only for b
