Question

If A=(1,2,3) B=(3,4) and C=(4,5,6) find A×(BnC)​

Answer 1

Answer:

A×(B∩C) = {(1,4),(2,4),(3,4)}

Step-by-step explanation:

∩ is Intersection that is common between two sets

B∩C = {3,4}∩{4,5,6}={4}

A×(B∩C) = {1,2,3}×{4}

A×(B∩C) = {(1,4),(2,4),(3,4)}

Answer 2

BnC= {4}

A×(BnC) = {(1,4),(2,4),(3,4)}
