Abstract:

The main purpose of this paper is using the analytic methods and the properties of Gauss sums to study the computational problem of one kind hybrid power mean of three-term character sums and two-term exponential sums, and give an exact computational formula for it. As an application of this result, we obtained a sharp upper bound estimate and lower bound estimates for the three-term character sums and two-term exponential sums
