Solution 2
Sure, I can help with that.
First, let's understand what P(P(A)) means. P(A) represents the power set of A, which is the set of all subsets of A.
Since A = {1}, the power set of A, P(A), is { {}, {1} }.
Now, we need to find the power set of P(A), which is P(P(A)).
The power set of P(A) is the set of all subsets of P(A), which is { {}, {{}}, {{1}}, { {}, {1} } }.
The number of elements in a set is represented by n(). So, n(P(P(A))) represents the number of elements in the power set of P(A).
Counting the elements in P(P(A)), we find there are 4 elements.
So, n(P(P(A))) = 4.
