यदि \(A={x:x\in\mathbb{Z},\ -3\le x<4}\) और \(B={x:x\in\mathbb{Z},\ x^2\le4}\), तो \(A\setminus B\) क्या है?
If \(A={x:x\in\mathbb{Z},\ -3\le x<4}\) and \(B={x:x\in\mathbb{Z},\ x^2\le4}\), what is \(A\setminus B\)?

Correct Answer
A. ({-3,3})
Concept
\(A=\{-3,-2,-1,0,1,2,3\}\) and \(B=\{-2,-1,0,1,2\}\), so the difference is ({-3,3}). Check the integer condition separately.
Why this answer is correct
The correct answer is A. ({-3,3}). \(A=\{-3,-2,-1,0,1,2,3\}\) and \(B=\{-2,-1,0,1,2\}\), so the difference is ({-3,3}). Check the integer condition separately.
Exam Tip
\(A=\{-3,-2,-1,0,1,2,3\}\) और \(B=\{-2,-1,0,1,2\}\), इसलिए अंतर ({-3,3}) है। पूर्णांक शर्त अलग से देखें।
