किस स्थिति में (\mathcal{P}(A)) में ठीक (16) तत्व होंगे?
In which case will (\mathcal{P}(A)) have exactly (16) elements?
Explanation opens after your attempt
Correct Answer
C. (n(A)=4)
Concept
\(2^4=16\), so (A) must have four elements. Remember the power set formula \(2^n\).
Why this answer is correct
The correct answer is C. (n(A)=4). \(2^4=16\), so (A) must have four elements. Remember the power set formula \(2^n\).
Exam Tip
\(2^4=16\) इसलिए (A) में चार तत्व होने चाहिए। घात समुच्चय का सूत्र \(2^n\) याद रखें।
