WitrynaSo suppose the square root of 2 is rational. Then x 2 = 2 has a solution in Q. Since Q embeds into every field of characteristic zero, x 2 = 2 has a solution in every field of characteristic zero, so ∃ x: x 2 = 2 is true in all such fields. On the other hand, take the set P of primes modulo which ∃ x: x 2 = 2 is false. WitrynaIn mathematics, an irrational number is a number that cannot be expressed as a simple fraction or ratio of two integers. These numbers, like π or √2, have in...
