Correct Answer

A. \(2\sqrt{7}\)

Step 1

Concept

\(\frac{3}{\sqrt{7}+2}=\sqrt{7}-2\) because the denominator becomes (7-4=3). Therefore the sum is \(2\sqrt{7}\).

Step 2

Why this answer is correct

The correct answer is A. \(2\sqrt{7}\). \(\frac{3}{\sqrt{7}+2}=\sqrt{7}-2\) because the denominator becomes (7-4=3). Therefore the sum is \(2\sqrt{7}\).

Step 3

Exam Tip

\(\frac{3}{\sqrt{7}+2}=\sqrt{7}-2\) है क्योंकि हर (7-4=3) बनता है। इसलिए योग \(2\sqrt{7}\) है।
