Explicação passo-a-passo:

$\mathsf{A = \{1,2,3,4\}}$

$\mathsf{B = \{3,4,5,6,7,8\}}$

$\mathsf{C = \{1,4,8\}}$

$\mathsf{a)\:A\:U\:B = \{1,2,3,4,5,6,7,8\}}$

$\mathsf{b)\:A\:U\:C = \{1,2,3,4,8\}}$

$\mathsf{c)\:B\:U\:C = \{1,3,4,5,6,7,8\}}$

$\mathsf{d)\:A - B = \{1,2\}}$

$\mathsf{e)\:A - C = \{2,3\}}$

Answer 2

A = {1,2,3,4} , B = { 3,4,5,6,7,8} , C = {1,4,8}

a) A U B =  {1,2,3,4,5,6,7,8}  

b) A U C = {1,2,3,4,8}

C) B U C =  {1, 3,4,5,6,7,8}  

d) A - B = {1,2}

e) A - C = {2,3}
