यदि \(A={\emptyset,{\emptyset},0}\) है तो (n(\mathcal{P}(A))) कितना होगा?
If \(A={\emptyset,{\emptyset},0}\), what is (n(\mathcal{P}(A)))?
Explanation opens after your attempt
C. (8)
Concept
(A) has three distinct elements \(\emptyset,{\emptyset},0\). Therefore (n(\mathcal{P}(A))=23=8).
Why this answer is correct
The correct answer is C. (8). (A) has three distinct elements \(\emptyset,{\emptyset},0\). Therefore (n(\mathcal{P}(A))=23=8).
Exam Tip
(A) में तीन अलग तत्व \(\emptyset,{\emptyset},0\) हैं। इसलिए (n(\mathcal{P}(A))=23=8) है।
