यदि \(x=\sqrt{3}+\sqrt{2}\) तो \(x^2-5\) क्या होगा?
If \(x=\sqrt{3}+\sqrt{2}\) then what is \(x^2-5\)?
Explanation opens after your attempt
Correct Answer
A. \(2\sqrt{6}\)
Concept
\(x^2=5+2\sqrt{6}\), hence the result is \(2\sqrt{6}\). Apply identities.
Why this answer is correct
The correct answer is A. \(2\sqrt{6}\). \(x^2=5+2\sqrt{6}\), hence the result is \(2\sqrt{6}\). Apply identities.
Exam Tip
\(x^2=5+2\sqrt{6}\) इसलिए उत्तर \(2\sqrt{6}\) है। सूत्र लागू करें।
