7. Let p and q be distinct odd primes. Let a є Z with god(a, M) = 1. Prove that if there exists b E ZM such that b2 a] in Zp, then there are exactly four distinct [r] E Zp such that Zp
C1= 5 C2= 6 C3= 10 GCD --> Greater Common Divisor B1 a. Let x := 3C1 + 1 and let y := 5C2 + 1. Use the Euclidean algorithm to determine the GCD (x, y), and we denote this integer by g. b. Reverse the steps in this algorithm to find integers a and b with ax + by = g. c. Use this to find the inverse of x modulo y. If the inverse doesn't exist why not?...
Problem 1 Let (A,) and (B, 3) be posets. Consider A x B as a poset under the product order - that is, (a, b) = (a',V) if and only if a < d' and b<W. (a) Suppose IE A is a minimal element and ye B is a minimal element. Prove that (2,4) is a minimal element of Ax B. (3 pts) (b) Suppose I E A is a maximal element and y E B is a maximal element....
This Question must be proven using mathematical induction 1: procedure GCD(a, b: positive integers) 2 if a b then return a 3: 4: else if a b then 5: return GCD (a -b, b) 6: else return GCD(a,b-a) 8: end procedure Let P(a, b) be the statement: GCD(a, b)-ged(a,b). Prove that P(a, b) is true for all positive integer a and b.
