[" If "R" is a relation from "A" to "B" and "],[n(A)=m,n(B)=n" then the number of "],[" possible relations from "A" to "B" is "]

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

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

If n(A)=2 and total number of possible relations from set A to B is 1024, then n(B) is

Given n(A)=3,n(B)=2, and the number of relations from A to B is x ,then x-60 is

If A={a,b,c}, B={m,n} find the number of relations from A to B.

If n(A) = p and n(B) = q , then the number of relations from set A to set B = ________.

If n(A) = 5 and n (B) = 7, then the number of relations on A*B is

" Let there be two sets "A&B" ,such that "A={a,b} & n(B)=4" ,then total number of possible relations defined from set "B" to set "A" is "
