यदि \(A=\{m,n\}\), तो (\mathcal{P}(A)) का कौन सा उपसमुच्चय नहीं है?
If \(A=\{m,n\}\), which is not a subset of (\mathcal{P}(A))?
Explanation opens after your attempt
Correct Answer
C. ({m,n})
Concept
(\mathcal{P}(A)={\emptyset,{m},{n},{m,n}}). The elements (m,n) are not in it, so ({m,n}) is not its subset.
Why this answer is correct
The correct answer is C. ({m,n}). (\mathcal{P}(A)={\emptyset,{m},{n},{m,n}}). The elements (m,n) are not in it, so ({m,n}) is not its subset.
Exam Tip
(\mathcal{P}(A)={\emptyset,{m},{n},{m,n}}) है। ({m,n}) के तत्व (m,n) इसमें नहीं हैं, इसलिए यह इसका उपसमुच्चय नहीं है।
