Answer 2

If A={1,2,3} then find A²

Answer:

A²= {(1,1) , (1,2), (1,3), (2,1) (2,2) ,(2,3), (3,1) ,(3,2), (3,3) }

Given:

A={1,2,3}

To find:

A²=?

Step-by-step explanation:

A Cartesian product of two sets A and B, written as A×B, is the set containing ordered pairs from A and B. That is, if C=A×B, then each element of C is of the form (x,y), where x∈A and y∈B: A×B={(x,y)|x∈A and y∈B}.

A x B = {(a,b): a∈A , b∈B }

A={1,2,3}

A²=A x A

{1,2,3} x {1,2,3}

A²= {(1,1) , (1,2), (1,3), (2,1) (2,2) ,(2,3), (3,1) ,(3,2), (3,3) }
