यदि \(q=\sqrt{11}+3\) है तो \(q^2-6q\) का मान क्या है?
If \(q=\sqrt{11}+3\), what is the value of \(q^2-6q\)?
Explanation opens after your attempt
A. (2)
Concept
\(q^2=20+6\sqrt{11}\) and \(6q=18+6\sqrt{11}\). Subtracting gives (2).
Why this answer is correct
The correct answer is A. (2). \(q^2=20+6\sqrt{11}\) and \(6q=18+6\sqrt{11}\). Subtracting gives (2).
Exam Tip
\(q^2=20+6\sqrt{11}\) और \(6q=18+6\sqrt{11}\) है। घटाने पर (2) मिलता है।
