यदि \(z=\sqrt{17}-\sqrt{6}\) है तो \(z^2\) का मान कौन-सा है?
If \(z=\sqrt{17}-\sqrt{6}\), which is the value of \(z^2\)?
Explanation opens after your attempt
A. \(23-2\sqrt{102}\)
Concept
(\(\sqrt{17}-\sqrt{6}\)2=17+6-2\sqrt{102}). The middle term remains negative.
Why this answer is correct
The correct answer is A. \(23-2\sqrt{102}\). (\(\sqrt{17}-\sqrt{6}\)2=17+6-2\sqrt{102}). The middle term remains negative.
Exam Tip
(\(\sqrt{17}-\sqrt{6}\)2=17+6-2\sqrt{102}) है। मध्य पद का चिन्ह ऋणात्मक रहेगा।
