यदि \(A=\{a,e,i,o,u\}\) है, तो (\mathcal{P}(A)) में कितने एक-तत्वीय समुच्चय होंगे?
If \(A=\{a,e,i,o,u\}\), how many singleton sets are in (\mathcal{P}(A))?
Explanation opens after your attempt
B. (5)
Concept
Each original element forms one singleton subset. From (5) elements, there are (5) singleton subsets.
Why this answer is correct
The correct answer is B. (5). Each original element forms one singleton subset. From (5) elements, there are (5) singleton subsets.
Exam Tip
हर मूल तत्व से एक एक-तत्वीय उपसमुच्चय बनता है। (5) तत्वों से (5) singleton subsets बनेंगे।
