यदि \(A={x:x\in\mathbb{R}\) और \(x^2+1=0}\) है तो वास्तविक संख्याओं में (A) क्या है?
If \(A={x:x\in\mathbb{R}\) and \(x^2+1=0}\), what is (A) in real numbers?
Explanation opens after your attempt
A. \(\varnothing\)
Concept
For no real (x), \(x^2+1=0\) is possible. The number system condition can change the answer.
Why this answer is correct
The correct answer is A. \(\varnothing\). For no real (x), \(x^2+1=0\) is possible. The number system condition can change the answer.
Exam Tip
किसी वास्तविक (x) के लिए \(x^2+1=0\) संभव नहीं है। संख्या पद्धति की शर्त उत्तर बदल सकती है।
