Sea el conjunto A={x∈R:  x son numeros primos menores a 15}A=\left\{x\in R:\ \ x\ son\ numeros\ primos\ menores\ a\ 15\right\} , por extensión sería:

A={2,3,5,7,11,13}A=\left\{2,3,5,7,11,13\right\}

A={1,2,3,5,7,11,13}A=\left\{1,2,3,5,7,11,13\right\}

A={2,3,5,7,13}A=\left\{2,3,5,7,13\right\}

A={2,3,5,7,11}A=\left\{2,3,5,7,11\right\}

Sea el conjunto A={x2−3:  x∈R,   −1≤x≤3}A=\left\{x^2-3:\ \ x\in R,\ \ \ -1\le x\le3\right\}

El conjunto por extensión es:

A={−2,−3,1,6}A=\left\{-2,-3,1,6\right\}

A={−2,−3,1,2,6}A=\left\{-2,-3,1,2,6\right\}

A={−2,−3,−2,1,6}A=\left\{-2,-3,-2,1,6\right\}

A={−2,−3,−1,2,6}A=\left\{-2,-3,-1,2,6\right\}

Dados los conjuntos A={1,2,3,4},  B={3,4,5,6},  C={2,4,6,8}A=\left\{1,2,3,4\right\},\ \ B=\left\{3,4,5,6\right\},\ \ C=\left\{2,4,6,8\right\}

El resultado de A∩B∩CA\cap B\cap C es:

A∩B∩C={4}A\cap B\cap C=\left\{4\right\}

A∩B∩C={3,4}A\cap B\cap C=\left\{3,4\right\}

A∩B∩C={3}A\cap B\cap C=\left\{3\right\}

A∩B∩C={ϕ}A\cap B\cap C=\left\{\phi\right\}
