... A number of the form 3s2 , where s is an integer, is called a one-third square. Show that u0 = 3 and u−4 = 12 are the only one-third squares in the sequence. Solution by the Proposer Assume that un = 3x2 . The proof is achieved in three stages. (a) Assume that n ≡ 1, 4, 6, −3, −2 (mod 14), n ≡ 2, 5, ...

... Proof. Case 1: x = 0. It is trivial that xed ≡ x mod N . Case 2: gcd(x, N ) = 1. Since ed ≡ 1 mod (p − 1)(q − 1), then ed = 1 + k(p − 1)(q − 1) for some k ∈ Z. Thus xed = x1+k(p−1)(q−1) = x(x(p−1)(q−1) )k Since x(p−1)(q−1) ≡ 1 mod N , we have xed ≡ x mod N. Case 3: gcd(x, N ) 6= 1. Since N = pq, we ...

We shall see that there are several different sorts of numbers: the natural numbers, the integers, the rational numbers, and the irrational numbers. We shall define these various sorts of numbers in this section. There is a so ...

... As a first example of a p-adic number for p = 7, we consider the quadratic congruences x2 ≡ 2 (mod 7k ) for k = 1, 2, 3 . . . . When k = 1 there are two solutions: x = x1 ≡ ±3 (mod 7). Any solution x2 to the congruence modulo 72 must also be a solution modulo 7, hence of the form x2 = x1 + 7y = ±3 + ...
