यदि \(A\subseteq U\), तो (\(A'\cup A\)') किसके बराबर है?
If \(A\subseteq U\), what is (\(A'\cup A\)') equal to?
Explanation opens after your attempt
Correct Answer
A. \(\varnothing\)
Concept
\(A'\cup A=U\). Therefore (\(A'\cup A\)'=U'=\varnothing).
Why this answer is correct
The correct answer is A. \(\varnothing\). \(A'\cup A=U\). Therefore (\(A'\cup A\)'=U'=\varnothing).
Exam Tip
\(A'\cup A=U\) होता है। इसलिए (\(A'\cup A\)'=U'=\varnothing) है।
