Resposta :
Se o conjunto e k= (1,2,3,4) o KxK que é pedido fica {1,2,3,4} x {1,2,3,4}
Desse jeito:
{(1,1) (1,2) (1,3) (1,4)}
{(2,1) (2,2) (2,3) (2,4)}
{(3,1) (3,2) (3,3) (3,4})
{(4,1) (4,2) (4,3) (4,4)}
Desse jeito:
{(1,1) (1,2) (1,3) (1,4)}
{(2,1) (2,2) (2,3) (2,4)}
{(3,1) (3,2) (3,3) (3,4})
{(4,1) (4,2) (4,3) (4,4)}
