Looks good, 5 -1 mod 37 is 15, so 2 (5) -1 mod 37 is 30. Thank you! I’m wondering if my answer is correct. The extended Euclidean Algorithm is usually what I have trouble on. It is definitely true that 2 ⨯ 5 -1 ≡ 30 mod 37. I don’t usually see this written as “2/5”, but it makes sense: the number 30 ...

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)
