alukav5142 [94]

Answer:

Bueno tus diagramas son mas de euler que de venn, por que les falta el conjunto universo. pero bueno para lógica matemática nos sirven ambos.

Para expresar por Extensión se ponen todos los elementos del conjunto.

Para tu ejercicio:

a)

Extensión

A={ 1 ; 4 ; 5 ; 12 }

B={4 ; 8 ; 12}  

Compresión

x / x ∈ AUB ⇔ x∈A  ó  x∈B  

b)  

Extensión

A={10,5,14}

B={5 ; 14}

Comprensión

x / x ∈ A ⇔ B⊂A ⇒ x ∈ B  

c)

Extensión

A={8 ; 9}

B={5 ; 15}

Comprensión

x / x ∈ A ⇔A⊄B

x / x ∈ B ⇔B⊄A
