Solution: Since p 6= q are prime numbers, we have gcd(p,q) = 1. By Fermat’s Little Theorem, pq−1 ≡ 1 (mod q) . Clearly qp−1 ≡ 0 (mod q) . Thus pq −1+qp ≡ 1 (mod q) . Exchanging the roles of p and q in the above argument, we prove that pq−1 +qp−1 ≡ 1 (mod p) . In other words, pq−1 + qp ...

Now imagine we take a = 11, b = 17. Both a and b are prime numbers. As a prime number has only itself and 1 as divisors, gcd(a,b) = 1. We say that for any two integers a,b, if gcd(a,b) = 1 then a and b are coprime integers. If a and b are prime, they are also coprime. townsend tubing river closedWebbSo, by a result from the book (Exercise 1, p110), p is even. That means there is some a 2Z such that p = 2a, so: 2(3q2) = (2a)2 = 4a2 3q2 = 2a2 That is, 3q2 is even. Since the product of two odd integers is odd, and 3 is odd, we see that q2 must be even, and so q itself is even. Then there exists some b 2Z such that q = 2b. But then 2 is a ... townsend turkey farm
