Correct Answer

A. \(\frac{\sqrt{7}-2}{3}\)

Step 1

Concept

Multiplying by the conjugate \(\sqrt{7}-2\) makes the denominator (7-4=3). So \(p=\frac{\sqrt{7}-2}{3}\).

Step 2

Why this answer is correct

The correct answer is A. \(\frac{\sqrt{7}-2}{3}\). Multiplying by the conjugate \(\sqrt{7}-2\) makes the denominator (7-4=3). So \(p=\frac{\sqrt{7}-2}{3}\).

Step 3

Exam Tip

संयुग्मी \(\sqrt{7}-2\) से गुणा करने पर हर (7-4=3) बनता है। इसलिए \(p=\frac{\sqrt{7}-2}{3}\) है।
