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
Correct Answer

C. (9)

Step 1

Concept

\(512=2^9\) so (n(A)=9). Always use the \(2^n\) rule for power set questions.

Step 2

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.

Step 3

Exam Tip

\(512=2^9\) इसलिए (n(A)=9) होगा। घात समुच्चय में हमेशा \(2^n\) नियम लगाएं।
