How many elements has P(A), if `A = phi` ?

Explanation

To solve the problem of how many elements the power set \( P(A) \) has when \( A = \emptyset \) (the empty set), we can follow these steps:

### Step 1: Understand the Power Set
The power set \( P(A) \) of a set \( A \) is the set of all possible subsets of \( A \).

### Step 2: Identify the Elements of Set \( A \)
In this case, the set \( A \) is given as \( \emptyset \), which means it has no elements.
