यदि \(U=\mathbb{R}\), (A=\(-\infty,-1]\cup[6,\infty\)), तो ((A')') क्या है?
If \(U=\mathbb{R}\), (A=\(-\infty,-1]\cup[6,\infty\)), what is ((A')')?
Explanation opens after your attempt
Correct Answer
A. (\(-\infty,-1]\cup[6,\infty\))
Concept
By the double complement law, ((A')'=A). Therefore the answer is the original set itself.
Why this answer is correct
The correct answer is A. (\(-\infty,-1]\cup[6,\infty\)). By the double complement law, ((A')'=A). Therefore the answer is the original set itself.
Exam Tip
द्वि-पूरक नियम के अनुसार ((A')'=A) होता है। इसलिए उत्तर वही मूल समुच्चय है।
