Question

Given A = {2, 3, 5}, B = {2, 5, 7}, C = {2, 6} and D = {2, 3, 7}. Is (A∩C)×(B∩D)=(A×C)∩
(B×D)A∩C×B∩D=A×C∩B×D true?​

Answer 1

Answer:

The given sets are:

A={1,2,4,5}, B={2,3,5,6}, C={4,5,6,7}

∴ B∪C={2,3,4,5,6,7}

A−(B∪C)={1}

A−B={1,4}

A−C={1,2}

(A−B)∩(A−C)={1}

we have to verify, A−(B∪C)=(A−B)∩(A−C)

LHS=A−(A∪C)

={1}

RHS=(A−B)∩(A−C)

={1}

Hence,

A−(B∪C)=(A−B)∩(A−C)
