यदि \(A={x:x\in\mathbb{Z}\) और \(x^2\leq 4}\) है तो (A) का कौन सा उपसमुच्चय उचित नहीं है?
If \(A={x:x\in\mathbb{Z}\) and \(x^2\leq 4}\), which subset of (A) is not proper?
Explanation opens after your attempt
Correct Answer
A. ({-2,-1,0,1,2})
Concept
Here \(A=\{-2,-1,0,1,2\}\), so the same set is a subset but not proper. A proper subset is not the whole set.
Why this answer is correct
The correct answer is A. ({-2,-1,0,1,2}). Here \(A=\{-2,-1,0,1,2\}\), so the same set is a subset but not proper. A proper subset is not the whole set.
Exam Tip
\(A=\{-2,-1,0,1,2\}\) है इसलिए वही समुच्चय उपसमुच्चय है पर उचित नहीं है। उचित उपसमुच्चय पूरा समुच्चय नहीं होता।
