| Abstract: |
| The fourth power mean of two-term exponential sums is studied in this paper. By elementary and algebraic methods, an explicit computation formula and a transform formula are proposed, which extend the original research results and discover the essential relation between fourth moment and congruence equations. |
| Key words: two-term exponential sums mixed exponential mean fourth power mean transform formula |
