Correct Answer

A. \(\frac{\sqrt{19}-4}{3}\)

Step 1

Concept

Multiplying by the conjugate makes the denominator (19-16=3). So \(p=\frac{\sqrt{19}-4}{3}\).

Step 2

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 \(p=\frac{\sqrt{19}-4}{3}\).

Step 3

Exam Tip

संयुग्मी से गुणा करने पर हर (19-16=3) बनता है। इसलिए \(p=\frac{\sqrt{19}-4}{3}\) है।
