dados os conjuntos A={-1,-2,-3} , B={-2,0,1,2} e C={-2,-1,4} , determine :
a)AUB=
b)AUBUC=
c)(AUB)-C=
d)AΠBΠC=
e)(AΠC) UB=​

Resposta :

BEAVNAGO

AUB = {-1, -2, -3, 0, 1, 2}

AUBUC = {-3, -2, -1, 0, 1, 2, 4}

(AUB)-C=  {-1, -2, -3, 0, 1, 2} - C = {-3, 0, 1 ,2}

AΠBΠC= {-2}

(AΠC) UB=​ {-1, -2} UB = {-2, -1, 0, 1 2}
