If `A={-1,2,3}and B={1,3}`, then determine
(i) `AxxB` (ii) `BxxA` (iii) `BxxB` (iv)`AxxA`

Answer 1

`A={-1,2,3,} and B ={1,3}`
(i) `AxxB={(-1,1),(-1,3),(2,1),(2,3),(3,1),(3,3)}`
(ii) `BxxA={(1,-1),(1,2),(1,3),(3-1),(3,2),(3,3)}`
(iii) `BxxB={(1,-1) ,(1,3),(3,1),(3,3)}`
(iv) `AxxA={(-1,-1),(-1,2),(-1,3),(2,-1),(2,2),(2,3),(3,-1), (3,2),(3,3)}`
