यदि `A = {1, 2}, B = {2, 3}, C = {3, 7)`, तो, ज्ञात करो।
(i) `(A xx B) uu (A xx C)` (ii) `(A xx B) nn (A xx C)`

Explanation

`A xx B = {(1, 2), (1, 3), (2, 2), (2, 3)}`
और `A xx C ={(1, 3), (1, 7), (2, 3), (2, 7)}`
(i) `(A xx B) uu (A xx C) = {(1, 2), (1, 3), (1, 7), (2, 2), (2, 3), (2, 7)}`
(ii) `(A xx B) nn(A xx C) = {(1, 3), (2, 3)}`
