Question

3. If G = {7, 8) and H = {5, 4, 2}, find G X H and H X G.

Plz plz please tell me answer right answer

Answer 1

Step-by-step explanation:

Answer

G={7,8} and H={5,4,2}

We know that the Cartesian product of P×Q of two non-empty sets P and Q is defined as

P×Q={(p,q):p∈P,q∈Q}

∴G×H={(7,5),(7,4),(7,2),(8,5),(8,4),(8,2)}

and H×G={(5,7),(5,8),(4,7),(4,8),(2,7),(2,8)}
