Question

If A={-1,1} B={0,2} c={0,1} then find (A×B) ^ (B×C).​

Answer 1

Answer

A={0,1}

B={1,2,3}

A×B={(0,1),(0,2),(0,3),(1,1),(1,2),(1,3)}

B×A={(1,0),(2,0),(3,0),(1,1),(2,1),(3,1)}

By the definition of equality of ordered pairs, the pair (0,1)  in A×B  is not equal to the pair (1,0) in  B×A

Therefore, A×B



=B×A
