यदि \(A={x:x\in\mathbb{Z},-3\le x\le 5}\) और \(B={x:x\in\mathbb{Z},x^2\le 9}\) है, तो \(A\setminus B\) क्या है?
If \(A={x:x\in\mathbb{Z},-3\le x\le 5}\) and \(B={x:x\in\mathbb{Z},x^2\le 9}\), then what is \(A\setminus B\)?
Explanation opens after your attempt
A. ({4,5})
Concept
Here \(B=\{-3,-2,-1,0,1,2,3\}\). Removing elements of (B) from (A) leaves ({4,5}).
Why this answer is correct
The correct answer is A. ({4,5}). Here \(B=\{-3,-2,-1,0,1,2,3\}\). Removing elements of (B) from (A) leaves ({4,5}).
Exam Tip
यहां \(B=\{-3,-2,-1,0,1,2,3\}\) है। (A) से (B) के तत्व हटाने पर ({4,5}) बचता है।
