Let n(A) = m, n(B) = n, then the total number of relations between A and B is `K^(mn)`, find K.

If n (A) =8: n(B) =2 then the total no. of relation that exists between A and B is :

Let n(A) = m and n(B) = n, then the number of non-empty relations from A to B is

Let n(A) = m and n(B) = n. Then the total number of non-empty relations that can be defined from A to B is

n(A)= m, n (B) = n. The total number of non empty relation from A to B is……..

Let n(A)=m and n(B)=n Then, the total number of non-empty relations that can be defined from A to B is:

Let n(A) = 6 and n(B) = p . Then , the total number of non - empty relations that can be defined from A to B is
