If \(A=\{{2},4,6\}\), what is (n(\mathcal{P}(A)))?
Explanation opens after your attempt
C. (8)
Concept
Set (A) has (3) elements so its power set has \(2^3=8\) elements. Count brackets carefully.
Why this answer is correct
The correct answer is C. (8). Set (A) has (3) elements so its power set has \(2^3=8\) elements. Count brackets carefully.
Exam Tip
(A) में (3) तत्व हैं इसलिए घात समुच्चय में \(2^3=8\) तत्व होंगे। कोष्ठकों को ध्यान से गिनें।
