यदि \(A={x:x\in\mathbb{Z}\) और \(0<x^2<10}\) तो (A) के बराबर कौन सा समुच्चय है?
If \(A={x:x\in\mathbb{Z}\) and \(0<x^2<10}\), which set is equal to (A)?
Explanation opens after your attempt
A. ({-3,-2,-1,1,2,3})
Concept
\(x^2\) can be (1,4,9), so \(x=\pm1,\pm2,\pm3\). Since \(0<x^2\), (0) is not included.
Why this answer is correct
The correct answer is A. ({-3,-2,-1,1,2,3}). \(x^2\) can be (1,4,9), so \(x=\pm1,\pm2,\pm3\). Since \(0<x^2\), (0) is not included.
Exam Tip
\(x^2\) (1,4,9) हो सकता है इसलिए \(x=\pm1,\pm2,\pm3\) हैं। \(0<x^2\) होने से (0) शामिल नहीं है।
