यदि \(q=\sqrt{6}+2\) है तो \(q^2-4q\) का मान क्या है?
If \(q=\sqrt{6}+2\), what is the value of \(q^2-4q\)?
Explanation opens after your attempt
A. (2)
Concept
\(q^2=10+4\sqrt{6}\) and \(4q=8+4\sqrt{6}\). Subtracting gives (2).
Why this answer is correct
The correct answer is A. (2). \(q^2=10+4\sqrt{6}\) and \(4q=8+4\sqrt{6}\). Subtracting gives (2).
Exam Tip
\(q^2=10+4\sqrt{6}\) और \(4q=8+4\sqrt{6}\) है। घटाने पर (2) मिलता है।
