If A = {2, 3}, which is the correct form of P(A)?
Answer and explanation
Correct answer: {∅, {2}, {3}, {2, 3}}
The power set is the set of all subsets, including the empty set and the original set itself. For A = {2, 3}, the subsets are ∅, {2}, {3}, and {2, 3}. Notice that 2 and 3 must appear inside braces when they are considered as singleton subsets. Therefore P(A) is option A, which correctly lists all four subsets.
