यदि \(U=\mathbb{R}\), (A=(-\infty,-4]\cup\(3,\infty\)), तो (A') क्या है?
If \(U=\mathbb{R}\), (A=(-\infty,-4]\cup\(3,\infty\)), what is (A')?
Explanation opens after your attempt
A. ((-4,3])
Concept
(A) includes (-4) and excludes (3). So the complement excludes (-4) and includes (3), giving ((-4,3]).
Why this answer is correct
The correct answer is A. ((-4,3]). (A) includes (-4) and excludes (3). So the complement excludes (-4) and includes (3), giving ((-4,3]).
Exam Tip
(A) में (-4) शामिल है और (3) शामिल नहीं है। इसलिए पूरक में (-4) नहीं और (3) शामिल होगा, अर्थात ((-4,3])।
