यदि \(z=\sqrt{23}-\sqrt{14}\) है तो \(z^2\) का मान कौन-सा है?
If \(z=\sqrt{23}-\sqrt{14}\), which is the value of \(z^2\)?
Explanation opens after your attempt
C. \(37-2\sqrt{322}\)
Concept
(\(\sqrt{23}-\sqrt{14}\)2=23+14-2\sqrt{322}). Keep the middle term negative.
Why this answer is correct
The correct answer is C. \(37-2\sqrt{322}\). (\(\sqrt{23}-\sqrt{14}\)2=23+14-2\sqrt{322}). Keep the middle term negative.
Exam Tip
(\(\sqrt{23}-\sqrt{14}\)2=23+14-2\sqrt{322}) है। मध्य पद का चिन्ह ऋणात्मक रखें।
