Nettet15. nov. 2024 · Prove that a^3 ≡ a (mod 3) for every positive integer a. What I did: Assume a^3 ≡ a (mod 3) is true for every positive integer a. Then 3a^3 ≡ 3a (mod 3). (3a^3 - 3a)/3 = k, where k is an integer a^3 - a = k Therefore, a^3 ≡ a (mod 3). Is this a valid method for proving? asked by Kid November 15, 2024 1 answer not really. Try this: Nettet30. jul. 2014 · 3 Answers Sorted by: 3 The problem with your argument is that your x in (1) is not an integer (unless you prove it). So even though you have 3 c b = ( c − b) 2 ( x 3 − 1), it does not imply that c − b divides 3 c b. Note also that c − b can divide c and b even for coprime c and b, contrary to what you say.
