    Rezolvarea congruenţelor pătrate în raport cu Modul Prim [Articol]
    (USARB, 2024) Cotos, Tatiana; Rotari, Tatiana, conducător şt.
    This paper explores methods for solving congruences with one variable, two variables, and n variables modulo a prime modulus. Within the study, various techniques and strategies for finding solutions to these types of congruences are presented. Among the discussed methods are the method of trials and the method of adding a multiple of the modulus. By providing a detailed presentation of these solution methods and techniques, this paper offers an in-depth perspective on solving congruences in the context of number theory, being useful for students, researchers in the field of mathematics.
