यदि \(p=\frac{1}{\sqrt{23}+4}\) है तो (p) का सरल रूप क्या है?
If \(p=\frac{1}{\sqrt{23}+4}\), what is the simplified form of (p)?
Explanation opens after your attempt
A. \(\frac{\sqrt{23}-4}{7}\)
Concept
Multiplying by the conjugate makes the denominator (23-16=7). So \(p=\frac{\sqrt{23}-4}{7}\).
Why this answer is correct
The correct answer is A. \(\frac{\sqrt{23}-4}{7}\). Multiplying by the conjugate makes the denominator (23-16=7). So \(p=\frac{\sqrt{23}-4}{7}\).
Exam Tip
संयुग्मी से गुणा करने पर हर (23-16=7) बनता है। इसलिए \(p=\frac{\sqrt{23}-4}{7}\) है।
