# If a set A and n

Answer :

The power set of set A is a collection of all subsets of A.

For example: if the set A is {1, 2} then all possible subsets of A would be {} (empty set), {1}, {2}, {1, 2}

Hence powerset of A that is P(A) will be {ϕ, {1}, {2}, {1,2}}

Now if the number of elements in set A is n then the number of elements in power set of A P(A) is 2n
