If `A= {-1, 3,4} and B={2,3}` then find `A xx B, B xx A and A xx A`

Text Solution

Verified by Experts

The correct Answer is:
`A xx B= {(-1, 2)(-1, 3)(3,2)(3,3) (4,2)(4,3)}`
`B xx A = {(2, -1) (3, -1) (2,3) (3,3) (2,4) (3,4)}`
`A xx A= {(-1, -1) (-1, 3)(-1, 4) (3,-1) (3,3) (3,4) (4, -1) (4,3) (4,4)}`
