यदि \(x=\sqrt{22}+\sqrt{10}\) है तो \(x^2-32\) का मान क्या है?
If \(x=\sqrt{22}+\sqrt{10}\), what is the value of \(x^2-32\)?
Explanation opens after your attempt
A. \(2\sqrt{220}\)
Concept
\(x^2=22+10+2\sqrt{220}=32+2\sqrt{220}\). So \(x^2-32=2\sqrt{220}\).
Why this answer is correct
The correct answer is A. \(2\sqrt{220}\). \(x^2=22+10+2\sqrt{220}=32+2\sqrt{220}\). So \(x^2-32=2\sqrt{220}\).
Exam Tip
\(x^2=22+10+2\sqrt{220}=32+2\sqrt{220}\) है। इसलिए \(x^2-32=2\sqrt{220}\) है।
