यदि \(A=\{क,ख,ग,घ\}\) है तो ({क,घ}) (\mathcal{P}(A)) में क्यों होगा?
If \(A=\{a,b,c,d\}\), why will ({a,d}) be in (\mathcal{P}(A))?
Explanation opens after your attempt
Correct Answer
A. क्योंकि यह (A) का उपसमुच्चय हैbecause it is a subset of (A)
Concept
All elements of ({a,d}) are in (A), so it is a subset. A power set contains all subsets.
Why this answer is correct
The correct answer is A. क्योंकि यह (A) का उपसमुच्चय है / because it is a subset of (A). All elements of ({a,d}) are in (A), so it is a subset. A power set contains all subsets.
Exam Tip
({क,घ}) के सभी तत्व (A) में हैं इसलिए यह उपसमुच्चय है। घात समुच्चय में सभी उपसमुच्चय आते हैं।
