Question

Considere os conjuntos A={-2,-1,0,1,2,3,4,5} B={0,1,3} c={3,4,5,6,7} obtenha o que se pede : a)AUB b)A∩C c)A-B d)B-A e)(AUB)∩C f)A∩B∩C

Answer 1

Resposta:

a) AUB={-2,-1,0,1,2,3,4,5}

b) A∩C={3,4,5}

c)A-B={-2,-1,2,4,5}

d)B-A= tudo que tem em b tem em a

e)(AUB))∩C={-2,-1,0,1,2,3,4,5})∩C={3,4,5}

f)A∩B∩C={3}
