Question

dado os conjuntos: A={3,4,5} B={2,6} C={1,5}
determine: AxB=
BxA=
AxC=
BxC=
BxB=

Answer 1

A = { 3,4,5} B = {2,6}  C = {1,5}

AxB = {(3,2), (3,6), (4,2), (4,6), (5,2), (5,6)}
BxA = {(2,3), (2,4), (2,5), (6,3), (6,4), (6,5)}
AxC = {(3,1), (3,5), (4,1), (4,5), (5,1), (5,5)}
BxC = {(2,1), (2,5), (6,1), (6,5)}
BxB = {(2,2), (2,6), (6,2), (6,6)}
