यदि \(A={x\in\mathbb{Z}: -6\le x\le6}\) और \(B={x\in\mathbb{Z}:x^2<10}\), तो (A-B) क्या है?
If \(A={x\in\mathbb{Z}: -6\le x\le6}\) and \(B={x\in\mathbb{Z}:x^2<10}\), what is (A-B)?
Explanation opens after your attempt
A. ({-6,-5,-4,4,5,6})
Concept
\(B=\{-3,-2,-1,0,1,2,3\}\). Removing it from (A) leaves ({-6,-5,-4,4,5,6}).
Why this answer is correct
The correct answer is A. ({-6,-5,-4,4,5,6}). \(B=\{-3,-2,-1,0,1,2,3\}\). Removing it from (A) leaves ({-6,-5,-4,4,5,6}).
Exam Tip
\(B=\{-3,-2,-1,0,1,2,3\}\) है। इसे (A) से हटाने पर ({-6,-5,-4,4,5,6}) बचता है।
