Given :    P(A), A का घात समुच्चय है और A शून्य समुच्चय है,

P(A) is power set of A

To Find :  P{P{P{P(A)}}} में कितने अवयव हैं?  

Number of elements in  P{P{P{P(A)}}}

(a).0

(b) 1

(c) 4

(d) 16​

Solution:

in n (A)  =  n

Then P(A)  = 2ⁿ

A शून्य समुच्चय है,

A is null set

=> n(A) =  0

=> P (A)  = 2⁰  = 1

P{P{P{P(A)}}}  = P{P{P{1}}}  

P(1)  = 2¹  = 2

P{P{P{P(A)}}}  = P{P{2}}  

P(2)  = 2²  = 4

P{P{P{P(A)}}}  = P{4}  

P(2)  = 2⁴  = 16

P{P{P{P(A)}}}  = 16

P{P{P{P(A)}}} में  16  अवयव हैं?  

Number of elements in  P{P{P{P(A)}}}  = 16
