समुच्चय \({x \in \mathbb{Z}:x^2=2}\) कैसा है?
What is the type of \({x \in \mathbb{Z}:x^2=2}\)?
Explanation opens after your attempt
A. रिक्त समुच्चयEmpty set
Concept
The real solutions of \(x^2=2\) are \(\sqrt{2}\) and \(-\sqrt{2}\).
Why this answer is correct
These are not integers.
Exam Tip
Since there is no integer solution, the set is empty. चरण 1: \(x^2=2\) के वास्तविक हल \(\sqrt{2}\) और \(-\sqrt{2}\) हैं। चरण 2: ये पूर्णांक नहीं हैं। चरण 3: पूर्णांकों में कोई हल न होने से समुच्चय रिक्त है।
