यदि \(A={x:x\in\mathbb{N},x^2\le 49}\) और \(B=\{2,4,6,8\}\) हैं, तो \(A\setminus B\) क्या है?
If \(A={x:x\in\mathbb{N},x^2\le 49}\) and \(B=\{2,4,6,8\}\), what is \(A\setminus B\)?
Explanation opens after your attempt
Correct Answer
A. ( {1,3,5,7} )
Concept
\(A=\{1,2,3,4,5,6,7\}\), and (2,4,6) are removed from it. Hence \(A\setminus B={1,3,5,7}\).
Why this answer is correct
The correct answer is A. ( {1,3,5,7} ). \(A=\{1,2,3,4,5,6,7\}\), and (2,4,6) are removed from it. Hence \(A\setminus B={1,3,5,7}\).
Exam Tip
\(A=\{1,2,3,4,5,6,7\}\) है, इसमें से (2,4,6) हटते हैं। इसलिए \(A\setminus B={1,3,5,7}\)।
