Question

A={p,{p}},then power set of A is​

Answer 1

Step-by-step explanation:

Answer:

16

Step-by-step explanation:

Given  

if p(a) denotes the power set of a, then find n(p(p(p(null set))))  

Let A = { } here A = n element and power set P(A) = 2^n

P(A) = 2^0 = 1 element

P(p(A)) = 2^1 = 2 elements

P(p(p(A)) = 2^2 = 4 elements

P(p(p(p(A)))) = 2^4 = 16 elements
