Question

DadososconjuntosA={5,6,7,8,9,10},B={9,10,11,12}eC={5,7,11, 13}, determine os elementos do conjunto:
(A ∩ B) U C - A

Answer 1

Resposta:

A={5,6,7,8,9,10} ,  B={9,10,11,12}   e   C={5,7,11, 13}

(A ∩ B)  ={9,10}

C - A = {11, 13}

(A ∩ B) U C - A

{9,10}  U  {11, 13}

= {9,10,11,13}

Answer 2

(A ∩ B) :

{9, 10}

C - A :

{11, 13}

(A ∩ B) U C - A:

{9, 10, 11, 13}
