यदि \(U=\mathbb{R}\) और \(A={x:-2<x\le 6}\), तो (A') क्या होगा?
If \(U=\mathbb{R}\) and \(A={x:-2<x\le 6}\), what is (A')?
Explanation opens after your attempt
Correct Answer
A. \((-\infty,-2]\cup\(6,\infty\))
Concept
(A) does not include (-2) but includes (6), so the complement includes (-2) but excludes (6). The correct answer is ((-\infty,-2]\cup\(6,\infty\)).
Why this answer is correct
The correct answer is A. \((-\infty,-2]\cup\(6,\infty\)). (A) does not include (-2) but includes (6), so the complement includes (-2) but excludes (6). The correct answer is ((-\infty,-2]\cup\(6,\infty\)).
Exam Tip
(A) में (-2) शामिल नहीं और (6) शामिल है, इसलिए पूरक में (-2) आएगा पर (6) नहीं आएगा। सही उत्तर ((-\infty,-2]\cup\(6,\infty\)) है।
