यदि \(p=\frac{1}{\sqrt{19}+4}\) है तो (p) का सरल रूप क्या है?
If \(p=\frac{1}{\sqrt{19}+4}\), what is the simplified form of (p)?
Explanation opens after your attempt
A. \(\frac{\sqrt{19}-4}{3}\)
Concept
Multiplying by the conjugate makes the denominator (19-16=3). So \(p=\frac{\sqrt{19}-4}{3}\).
Why this answer is correct
The correct answer is A. \(\frac{\sqrt{19}-4}{3}\). Multiplying by the conjugate makes the denominator (19-16=3). So \(p=\frac{\sqrt{19}-4}{3}\).
Exam Tip
संयुग्मी से गुणा करने पर हर (19-16=3) बनता है। इसलिए \(p=\frac{\sqrt{19}-4}{3}\) है।
