Explanation opens after your attempt
A. (1)
Concept
\(q^2=19+6\sqrt{10}\) and \(6q=18+6\sqrt{10}\). Subtracting gives (1).
Why this answer is correct
The correct answer is A. (1). \(q^2=19+6\sqrt{10}\) and \(6q=18+6\sqrt{10}\). Subtracting gives (1).
Exam Tip
\(q^2=19+6\sqrt{10}\) और \(6q=18+6\sqrt{10}\) है। घटाने पर (1) मिलता है।
