Question

verify that for two sets A and B, n(A×B)=pq where n(A)=p and n(B)=q the total number of relationships from A to B is 2pq​

Answer 1

Answer:

Step-by-step explanation:Taking left hand side ,we get_

n(A×B)

by using distributive identity (a(b+c) =A×B +A×C)

n×A +n×B

by putting values of n(a) and n(b) in the equation ,we get_

p×q

=pq

Here, pq =pq

LHS = RHS

Hence, verified.
