यदि \(A=\{4,6,8\}\) है तो (\mathcal{P}(A)) में कितने तत्व होंगे?
If \(A=\{4,6,8\}\) then how many elements will be in (\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. Use the \(2^n\) rule directly in exams.
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. Use the \(2^n\) rule directly in exams.
Exam Tip
(A) में (3) तत्व हैं इसलिए घात समुच्चय में \(2^3=8\) तत्व होंगे। परीक्षा में \(2^n\) नियम तुरंत लगाएं।
