Question

Sendo A = {1, 2}, B = {2, 3}, C = {1, 3, 4} e D = {1, 2, 3, 4}, classificar em V ou F cada sentença abaixo e justificar: A ⊂ D b) A ⊂ B c) B ⊂ C d) D ⊃ B e) C = D f) A ⊄ C

Answer 1

$\bf A = \{ 1,2\} \\\bf B = \{2,3\} \\ \bf C = \{1 ,3,4\} \\ \bf D = \{1 ,2,3,4\}$

a)

$\Large \boxed{\green{ \bf A ⊂ D \: (V)}}$

b)

$\Large \boxed{\green{ \bf A ⊂ B \: ( F)}}$

c)

$\Large \boxed{ \green{\bf B ⊂ C \: (F)}}$

d)

$\Large \boxed{\green{\bf D ⊃ B \: (V )}}$

e)

$\Large \boxed{\green{ \bf C = D \: (F )}}$

f)

$\Large \boxed{\green{\bf A ⊄ C \: ( V)}}$
