If `n(A)=6` and n(B)=3, then find the number of subsets of `A xx B`.

If A and B are two sets such that n(A)=2 and n(B)=4 , then the total number of subsets of AxxB each having at least 3 elements are

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

Let A and B be two finite sets such that A cap B is a singleton. If n(A) = 6, n(B) = 4, then number of subsets of A Delta B is

n(A)=3 then number of proper subsets of A is……………

Two sets A and B are such that n(A) = m and (B) = k. If the number of subsets A and B is! 144, find the values of m and k.

If n (A Delta B) = 12 and n(A nn B) = 3 , then find the greatest possible value of n(A xx B) .

If N={a,b,c,..z} then find the number of all possible subsets of N.
