यदि \(A={\emptyset,{\emptyset}}\) है तो (n(\mathcal{P}(A))) कितना होगा?
If \(A={\emptyset,{\emptyset}}\), what is (n(\mathcal{P}(A)))?
Explanation opens after your attempt
B. (4)
Concept
(A) has two distinct elements \(\emptyset\) and \({\emptyset}\). Therefore (n(\mathcal{P}(A))=22=4).
Why this answer is correct
The correct answer is B. (4). (A) has two distinct elements \(\emptyset\) and \({\emptyset}\). Therefore (n(\mathcal{P}(A))=22=4).
Exam Tip
(A) में दो अलग तत्व \(\emptyset\) और \({\emptyset}\) हैं। इसलिए (n(\mathcal{P}(A))=22=4) है।
