Answer 2

Answer:

If A={1,3,5}

B={2,3}

A×B={1,3,5}×{2,3}

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

B×A={2,3}×{1,3,5}

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

A×A={1,3,5}×{1,3,5}

={(1,1),(1,3),(1,5),(3,1),(3,3),3,5),(5,1),

(5,3),(5,5)}

B×B={2,3}×{2,3}

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

A×A×A={A×(A×A)}

={1,3,5}×{(1,1),(1,3),(1,5),(3,1),(3,3),(3,5),

(5,1),(5,3),(5,5)}
