Question

Prove that square root of n is irrational

Answer 1

Answer:

Step-by-step explanation:

Prove that the square root of a positive integer is either an integer or irrational. ... That is, we suppose that the square root of any non-square number is rational. So √n=ab, where a,b∈Z+,b≠0. We also suppose that a≠0, otherwise ab=0 , and n will be a square number, which is rational.
