Question

if a = {pi}then, p(p(p(pi)))=?
​

Answer 1

Answer:

4elements

Step-by-step explanation:

a is the set

p(a)=power set of A

collection of all the sub set of A

A=n elements

>>p(A)=2^n

>>n(p(A)=2^n

>>(pi)=0elements

>>p(pi)=2^0=1

>>p(p(pi))=2^1=2elements

>>p(p(p(pi)))=2^2=4elements

=>>>p(p(p(p(pi)))=4elements
