यदि \(A={\varnothing,{\varnothing}}\) है तो (P(A)) में कौन सा अवयव अवश्य होगा?
If \(A={\varnothing,{\varnothing}}\) then which element must belong to (P(A))?
Explanation opens after your attempt
Correct Answer
A. \({{\varnothing}}\)
Concept
Elements of (P(A)) are subsets of (A), and \({{\varnothing}}\) is a subset of (A). In a power set, elements are always subsets.
Why this answer is correct
The correct answer is A. \({{\varnothing}}\). Elements of (P(A)) are subsets of (A), and \({{\varnothing}}\) is a subset of (A). In a power set, elements are always subsets.
Exam Tip
(P(A)) में (A) के उपसमुच्चय अवयव बनते हैं और \({{\varnothing}}\) (A) का उपसमुच्चय है। पावर सेट में अवयव हमेशा उपसमुच्चय होते हैं।
