यदि (n(\mathcal{P}(A))=512) है, तो (n(A)) का मान क्या होगा?
If (n(\mathcal{P}(A))=512), what is the value of (n(A))?
Explanation opens after your attempt
C. (9)
Concept
\(512=2^9\) so (n(A)=9). Always use the \(2^n\) rule for power set questions.
Why this answer is correct
The correct answer is C. (9). \(512=2^9\) so (n(A)=9). Always use the \(2^n\) rule for power set questions.
Exam Tip
\(512=2^9\) इसलिए (n(A)=9) होगा। घात समुच्चय में हमेशा \(2^n\) नियम लगाएं।
