Use the well-ordering principle to show that (Z, +, ≤) is an Archimedean group, that is, prove that, for every a, b ∈ Z > 0, there exists n ∈ N such that na > b. Hint: argue by contradiction and consider the set X = {b-na: n ∈ N}. 2 tabg cheats 2022WebLet n ∈ Nand a,b,c ∈ Z. If (c,n) = 1, then ac ≡ bc (mod n) ⇔ a ≡ b (mod n). Proof. If ac ≡ bc (mod n), then n ac −bc = (a −b)c. Since (c,n) = 1, Euclid’s lemma implies that n a−b, which means a ≡ b (mod n). The reverse implication follows immediately from part 2 of Theorem 3.
