there are 14 elements in A × B.if n(A) > n(B) and B is not singleton set find n(A) and n(B) help me out...
The only factors of 14, in pairs, are (1, 14) and (2, 7). n(A) * n(B) = 14, and we have n(A) > n(B), so n(B) must be either 1 or 2. But if n(B) = 1, B is a singleton set, so n(B) = 2 and n(A) = 7.
