WebMay 13, 2016 · There is also a nice formula giving solutions for quadratic residues modulo n: x = a ( p − 1) ( q − 1) + 4 8 mod n. As usual, it is sufficient to verify it modulo p and modulo q separately.

WebThis can be used to prove that a relation is never true by finding a suitable modulus, or to derive conditions on the potential solutions of the equation. Example: by choosing an … WebIn modular arithmetic this operation is equivalent to a square root of a number (and where x is the modular square root of a modulo p ). For example, if we have a = 969 and p = 1223, we get: x 2 = 968 ( mod 1223) For this we get a solution of: 453 2 = 968 ( mod 1223) If we have a = 1203 and p = 1223, we get: x 2 = 1203 ( mod 1223)
