Answer 1

Dados de conjuntos A={2,3,5,7,9} , B={2,4,6,8,10} e C={1,2,3,4,5,6,7,8,9,10} , determine. 

A) A u B = (2; 3; 4; 5; 6; 7; 8; 9; 10)

B) A n B = (2)

C) (A n B) u C = (2) u (1; 2; 3; 4; 5; 6; 7; 8; 9; 10)

D) B - A = (4; 6; 8; 10)

E) (A u C)-B = (1,2,3,4,5,6,7,8,9,10) - (2,4,6,8,10) = (1; 3; 5; 7; 9)

F) (A u B) n C =(2; 3; 4; 5; 6; 7; 8; 9; 10) n (1; 2; 3,4,5,6,7,8,9,10) = (2; 3; 4; 5; 6; 7; 8; 9; 10)

G)(B - C ) u A = ∅ u A = (∅; 2,3,5,7,9)
