यदि \(A=\{9,18,27\}\) है, तो \(A-\varnothing\) क्या है?
If \(A=\{9,18,27\}\), what is \(A-\varnothing\)?
Explanation opens after your attempt
A. ( {9,18,27} )
Concept
There is no element in \(\varnothing\) to remove, so \(A-\varnothing=A\). In difference, check the removing set carefully.
Why this answer is correct
The correct answer is A. ( {9,18,27} ). There is no element in \(\varnothing\) to remove, so \(A-\varnothing=A\). In difference, check the removing set carefully.
Exam Tip
\(\varnothing\) से कोई अवयव हटाने के लिए नहीं है, इसलिए \(A-\varnothing=A\) है। अंतर में हटाए जाने वाले समुच्चय को ध्यान से देखें।
