यदि \(p=\frac{1}{\sqrt{13}+3}\) है तो (p) का सरल रूप कौन-सा है?
If \(p=\frac{1}{\sqrt{13}+3}\), which is the simplified form of (p)?
Explanation opens after your attempt
A. \(\frac{\sqrt{13}-3}{4}\)
Concept
Multiplying by the conjugate \(\sqrt{13}-3\) makes the denominator (13-9=4). So \(p=\frac{\sqrt{13}-3}{4}\).
Why this answer is correct
The correct answer is A. \(\frac{\sqrt{13}-3}{4}\). Multiplying by the conjugate \(\sqrt{13}-3\) makes the denominator (13-9=4). So \(p=\frac{\sqrt{13}-3}{4}\).
Exam Tip
संयुग्मी \(\sqrt{13}-3\) से गुणा करने पर हर (13-9=4) बनता है। इसलिए \(p=\frac{\sqrt{13}-3}{4}\) है।
