Correct Answer

A. \(25k^2\)

Step 1

Concept

We have (p=5k).

Step 2

Why this answer is correct

Squaring gives (p-2=(5k)2=25k-2).

Step 3

Exam Tip

Do this simplification carefully in the proof of \(\sqrt{5}\). चरण 1: (p=5k) दिया है। चरण 2: वर्ग करने पर (p-2=(5k)2=25k-2)। चरण 3: \(\sqrt{5}\) के प्रमाण में यह सरलीकरण ध्यान से करें।
