Step-by-step explaination:
(i) Let 12√12 is a rational number. 12√12 = p/q √2 = q/p By Squaring on both sides, 2 × p2 = q2 2, divides q2 . ∴ 2, divides q ∵ q is an even number. Similarly ‘p’ is an even number. ∴ p and q are even numbers. ∴ Common factor of p and q is 2. This contradicts the fact that p and q also irrational.
∴ √2 is an irrational number.
∴ 12√12 is an irrational number.
