We have A={1,2,3} and B={3,4}

A×B={(1,3),(1,4),(2,3),(2,4),(3,3),(3,4)}

We have A={1,2,3} and C={1,3,5}

A×C={(1,1),(1,3),(1,5),(2,1),(2,3),(2,5),(3,1),(3,3),(3,5),}

Now,(A×B)∩(A×C)

={(1,3),(1,4),(2,3),(2,4),(3,3),(3,4)}∩{(1,1),(1,3),(1,5),(2,1),(2,3),(2,5),(3,1),(3,3),(3,5),}

={(1,3),(2,3),(3,3)}
