Stack Exchange network … WebOct 22, 2016 · As neither a0 nor b0 is divisible by 3, then by the uniqueness of the prime factorization of integers, we have 2kb + 1 = 2ka. However, as the left hand side of this is an odd number and the right is even, we have reached a contradiction. Thus our initial premise was false, meaning √3 is not rational, i.e., √3 is irrational. ∎ Answer link Beaker M. WebHence show that 3 — √2 is irrational. Answer: The definition of irrational is a number that does not have a ratio or for which no ratio can be constructed. That is, a number that cannot be stated in any other way except by using roots. To put it another way, irrational numbers cannot be represented as a ratio of two integers. martineta común
