WebProve if n2 is odd then n is odd. Proof (proof by contradiction): Assume n2 is odd and n is even. integer k n = 2k n2 = 4k2 = 2(2k2) Let m = 2k2. n2 = 2m So, n2 is even. Let p is “n2 is odd ”. p ¬p is a contradiction. By contradiction, if n2 is odd then n is odd. WebIf the set A has 3 elements and the set B {3, 4, 5}, then find the number of elements in (A x B). Solution. According to question, n (A) = 3 and n (B) = 3. ∴ n (A x B) = n (A) x n (B) = 3 x 3 = 9 ∴ There are total 9 elements in (A x B). Ex 2.1 Class 11 Maths Question 3.
