Question

Dados os conjuntos a={0,2,4,6,8} e b={1,3,5,7,9}, use o simbolo E ou E/ para relacionar: A) 6 e A ( ) B) 6 e B ( ) C) 4 e A ( ) D) 4 e B ( ) E) 7 e A ( ) F) 5 e B ( )

Answer 1

I will answer in English.

We have the sets:

a = {0, 2, 4, 6, 8}

b = {1, 3, 5, 7, 9}

So a is the set of the even numbers, and b the set of the odd numbers.

We must use the symbols ∈ and ∉ to each option:

A) 6 ∈ a (this means, 6 is an object in the set a)

B) 6 ∉ b (this means, 6 is not an object in the set b)

C) 4 ∈ a

D) 4 ∉ b

E) 7 ∉ a

E) 5 ∈ b
