 If A={x²1:x€N 1≤x≤5} write number of subsets of 'A'
 Let A = {1, 2, 3}. Is ?
 If A = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}, write a subset B of A that contain all multiples of 3.
 Two finite sets have m and n elements. The total number of subsets of the first set is 112 more than the total number of subsets of the second set. Find the values of m and n.
 How many elements has P(A), if A = {1}.
