यदि (n(\mathcal{P}(A))=32), तो (n(A)) क्या है?
If (n(\mathcal{P}(A))=32), what is (n(A))?
Explanation opens after your attempt
Correct Answer
B. (5)
Concept
We have (n(\mathcal{P}(A))=2^{n(A)}). Since \(32=2^5\), (n(A)=5).
Why this answer is correct
The correct answer is B. (5). We have (n(\mathcal{P}(A))=2^{n(A)}). Since \(32=2^5\), (n(A)=5).
Exam Tip
(n(\mathcal{P}(A))=2^{n(A)}) होता है। \(32=2^5\), इसलिए (n(A)=5) है।
