यदि \(r=\frac{1}{\sqrt{11}+3}\) है, तो (r) का सरल रूप कौन-सा है?
If \(r=\frac{1}{\sqrt{11}+3}\), which is the simplified form of (r)?
Explanation opens after your attempt
Correct Answer
A. \(\frac{\sqrt{11}-3}{2}\)
Concept
Multiplying by the conjugate makes the denominator (11-9=2). So the simplified form is \(\frac{\sqrt{11}-3}{2}\).
Why this answer is correct
The correct answer is A. \(\frac{\sqrt{11}-3}{2}\). Multiplying by the conjugate makes the denominator (11-9=2). So the simplified form is \(\frac{\sqrt{11}-3}{2}\).
Exam Tip
संयुग्मी से गुणा करने पर हर (11-9=2) बनता है। इसलिए सरल रूप \(\frac{\sqrt{11}-3}{2}\) है।
