Correct Answer

A. \(6\sqrt{5}\)

Step 1

Concept

\( \sqrt{20}=2\sqrt{5} \) and \( \sqrt{45}=3\sqrt{5} \). The total coefficient is (1+2+3=6), so the value is \(6\sqrt{5}\).

Step 2

Why this answer is correct

The correct answer is A. \(6\sqrt{5}\). \( \sqrt{20}=2\sqrt{5} \) and \( \sqrt{45}=3\sqrt{5} \). The total coefficient is (1+2+3=6), so the value is \(6\sqrt{5}\).

Step 3

Exam Tip

\( \sqrt{20}=2\sqrt{5} \) और \( \sqrt{45}=3\sqrt{5} \)। कुल (1+2+3=6) से \(6\sqrt{5}\) मिलता है।
