## Abstract In this paper we present a new method for evaluating exponential sums associated to a restricted power series in one variable modulo __p__^__l__^ , a power of a prime. We show that for sufficiently large __l__, these sums can be expressed in terms of Gauss sums. Moreover, we study the a
