यदि \(A=\{2,3,5\}\) है तो (2) और ({2}) में से (\mathcal{P}(A)) का तत्व कौन है?
If \(A=\{2,3,5\}\), which among (2) and ({2}) is an element of (\mathcal{P}(A))?
Explanation opens after your attempt
Correct Answer
B. केवल ({2})only ({2})
Concept
(\mathcal{P}(A)) contains subsets so ({2}) is correct. (2) is an element of (A) but not of the power set.
Why this answer is correct
The correct answer is B. केवल ({2}) / only ({2}). (\mathcal{P}(A)) contains subsets so ({2}) is correct. (2) is an element of (A) but not of the power set.
Exam Tip
(\mathcal{P}(A)) में उपसमुच्चय होते हैं इसलिए ({2}) सही है। (2) (A) का तत्व है लेकिन घात समुच्चय का तत्व नहीं।
