Question

If G = {1, 87 H = 25, 4, 29 Find G x H and HxGIf G = { 7, 8) and H = {5, 4, 2} find G x H and HxG
​​

Answer 1

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)}
