Question

Obtenha A n B, AUB,A-B,B-A nos seguintes casos
a) {-2,-1,0,1,2} e B {0,1,2,3,4}
B) [-5 sobre 6, 2 sobre 3] e B [-√2,√3]

Answer 1

A) AnB= {0,1,2}
AuB= {-2,-1,0,1,2,3,4}
A-B= {-2,-1}
B-A= {3,4}

B)AuB= {-5/6, 2/3, - raiz de 2, raiz de 3}.
AnB= { }
A-B= {-5/6, 2/3}
B-A= { - raiz de 2, raiz de 3}
