Question

. If G={1,2,3,4} and H={7,6,5,4} then, GUH is *​

Answer 1

$\huge\star\underline{\orange{❥︎a}\mathfrak\blue{n}\mathfrak\purple{S}\mathbb\pink{wer}}\star\:$

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)}
