..If A and B are two non empty sets having N elements in common. Prone that A×B andB×A having n^2 elements in common​

Answer 1

Answer:

If both have same number of elements and same elements that shows A=B so A×A =A²

So both will have n² number of elements

Answer 2

Answer:

Let A and B be two non-empty sets having n elements in common, then prove that A x B and B x A have n2 elements in common. Hence, A x B and B x A have n2 elements in common. ... The Cartesian product A × A has 9 elements among which are found (–1, 0) and (0,1).
