Question

if a is equal to (1,3) and b is equal to (4,6) then a x b and b x a​

Answer 1

concept: if A ={a,b} and B= {c, d }

then, A × B = {(a,c), (a, d), (b, c), (b, d)}

(i) A = {1, 2, 3} and B = {2, 4}

then, A × A = {(1,1), (1,2), (1,3), (2,1), (2,2), (2,3), (3,1), (3,2), (3,3)}

A × B = {(1, 2), (1,4), (2,2), (2,4), (3, 2), (3, 4)}

B × A = {(2, 1), (2,2), (2,3), (4,1), (4,2), (4,3)}

B × B = {(2,2), (2,4), (4,2), (4,4)}

(A × B) \cap∩ (B × A) = (2,2)
