1 Sabendo que A = {0,1,2,5,6}, B = {7,8,9}, C = {2,4,6,8}, D = {1,3,7,9} e E = {2,3,5,7}, obtenha (B U C) ∩ A:


2 Sabendo que A = {0,1,2,5,6}, B = {7,8,9}, C = {2,4,6,8}, D = {1,3,7,9} e E = {2,3,5,7}, obtenha (D ∩ E) U B:

Answer 1

1)   (B U C) ∩ A

    = {2,4,6,7,8,9} ∩ {A 2,6}

2)   (D ∩ E) U B

    ={3,7} U B {3,7,8,9}
