यदि (n(\mathcal{P}(A))=64) और (U) में (10) तत्व हैं, तो (A') में कितने तत्व होंगे?
If (n(\mathcal{P}(A))=64) and (U) has (10) elements, how many elements are in (A')?
Explanation opens after your attempt
A. (4)
Concept
Since \(2^{n(A)}=64\), (n(A)=6), so (n(A')=10-6=4). In exams, identify the universal set first.
Why this answer is correct
The correct answer is A. (4). Since \(2^{n(A)}=64\), (n(A)=6), so (n(A')=10-6=4). In exams, identify the universal set first.
Exam Tip
क्योंकि \(2^{n(A)}=64\), इसलिए (n(A)=6) और (n(A')=10-6=4)। परीक्षा में पहले आधार समुच्चय को पहचानें।
