alukav5142 [94]

Answer:

Esta es mi respuesta quizá hay respuestas que difieran de la mía .

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.

A ver:

Para representar por Compresión, expresamos la principal característica global que define a los elementos del conjunto con simbología o escritura.

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
