$A$

$=$

$\{2, 5, 7\}$ and

$B$

$=$

$\{7, 3\}$ , then find.

(i)

$A \times B$

$=$

$\{(i, i), (i, i), (i, i), (i, i), (i, i), (i, i)\}$

[Note: Enter the first coordinates in the ascending order and the second coordinates in the descending order.]

(ii)

$B \times A$

$=$

$\{(i, i), (i, i), (i, i), (i, i), (i, i), (i, i)\}$

[Note: Enter the first coordinates in the descending order and the second coordinates in the ascending order.]

(iii)

$n(B \times A)$
