Answer 1

Ello user !!!!!!!!

Here is your answer,

============================================

If A=Ф that means A does not contain any element i.e., n=0.

Now, number of elements in a power set is 2ⁿ.

∴, n[P(A)]=2⁰=1

Therefore P(A) contains 1 element.

============================================

HOPE THIS HELPS YOUU :)
