If A={1,2,3} then the number of elements in P(A) is

If A = {1, 2, 3, 4} then the number of elements in A xx A is

If A={1,3,5,6} , the number of elements in P{P(A)} is

If A={1,2},P(A) denotes power set of A ,then the number of elements in P(P(P(P(A))) is 2^256 2^1024 2^512 2^(2^16)

If A = phi , then the number elements in P(A), (i.e., the number of elements in the power set of A) is

When A= phi then number of elements in P(A) is

If A={1,2,3,4}, then the number of substets of A that contain the element 2 but not 3, is

When A= phi , then number of elements in P(A) is………..

If A={ p in N,p is a prime and p=(7n^(2)+3n+3)/(n) for some n in N ), then the number of elements in the set A is

If {p in N: "p is a prime" and p=(7n^(2)+3n+3)/(n)"for some n" in N}' then the number of elements in the set A, is

If {p in N: "p is a prime" and p=(7n^(2)+3n+3)/(n)"for some n" in N}' then the number of elements in the set A, is
