Math Problem Statement
What is the value of P(P(∅)), where P is the power set and ∅ is the empty set?
Solution
The expression provided is , where denotes the power set and represents the empty set.
Let's solve it step by step:
-
Find :
- The power set of a set is the set of all subsets of .
- The empty set, , has only one subset: itself. Thus, the power set of the empty set is .
-
Find :
- Now we need to find the power set of .
- The set has two subsets: the empty set and the set itself .
- Therefore, .
Hence, the final result is:
