Finding A, B from A x B

Last updated at December 16, 2024 by

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

 

Then,

A = Set of first elements = {1, 2, 3}

B = Set of second element = {3, 4}

 

Let us check

If A = {1, 2, 3}, B = {3, 4}

A  × B = {(1, 3), (1, 4),

        (2, 3), (2, 4),

        (3, 3), (3, 4)}

Which is the same as above.
