Question

If () = 2 − 3 + 1 ,find ∈ such that (2) = ().

Answer 1

Answer:

It is given that n(A)=3 and n(B)=2 and (x,1),(y,2),(z,1) are in A×B 

We know that A= Set of first elements of the ordered pair elements of A×B

B= Set of second elements of ordered pair elements of A×B

∴x,y and z are the elements of A and 1 and 2 are the elements of B

Since n(A)=3 and n(B)=2 it is clear that A={x,y,z} and B={1,2}
