Q5 of 76 Page 3

If A = {1, 2} and B = {1, 3}, find A x B and B x A.

Given A = {1, 2} and B = {1, 3}

To find: A × B, B × A

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

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

If a ∈ { - 1, 2, 3, 4, 5} and b ∈ {0, 3, 6}, write the set of all ordered pairs (a, b) such that a + b = 5.

If a ∈ {2, 4, 6, 9} and b ∈{4, 6, 18, 27}, then form the set of all ordered pairs (a, b) such that a divides b and a<b.

Let A = {1, 2, 3} and B = {3, 4}. Find A x B and show it graphically

If A = {1, 2, 3} and B = {2, 4}, what are A x B, B x A, A x A, B x B, and (A x B) ∩ (B x A)?
