ME AJUDAAAAA!

considerando os conjuntos A={-1,-2,0} Bê={3,-2,0,1} e C={2,-3}. Escreva os produtos cartesianos

A x B=____________________B x A=_________________

B x C=____________________C x C=_________________​

Answer 1

Resposta:

1) A x B = [ (-1,3), (-1,-2), (-1,0), (-1,1), (-2,3), (-2,-2), (-2,0), (-2,1), (0,3), (0,-2), (0,0), (0,1) ]

2) B x A = [ (3,-1), (3,-2), (3,0), (-2,-1), (-2,-2), (-2,0), (0,-1), (0,-2), (0,0), (1,-1), (1,-2), (1,0) ]

3) B x C = [ (3,2), (3,-3), (-2,2), (-2,-3), (0,2), (0,-3), (1,2), (1,-3) ]

4) C x C = [ (2,2), (2,-3), (-3,2), (-3,-3) ]
