यदि \(A={x:x\in\mathbb{Z},-3\le x\le2}\) और \(B={x:x\in\mathbb{Z},x^2\le4}\) हैं, तो \(A\cup B\) क्या है?
If \(A={x:x\in\mathbb{Z},-3\le x\le2}\) and \(B={x:x\in\mathbb{Z},x^2\le4}\), what is \(A\cup B\)?

Correct Answer
A. ( {-3,-2,-1,0,1,2} )
Concept
\(A=\{-3,-2,-1,0,1,2\}\) and \(B=\{-2,-1,0,1,2\}\). Therefore \(A\cup B=A\).
Why this answer is correct
The correct answer is A. ( {-3,-2,-1,0,1,2} ). \(A=\{-3,-2,-1,0,1,2\}\) and \(B=\{-2,-1,0,1,2\}\). Therefore \(A\cup B=A\).
Exam Tip
\(A=\{-3,-2,-1,0,1,2\}\) और \(B=\{-2,-1,0,1,2\}\) है। इसलिए \(A\cup B=A\) है।
