What is the simplified form of \( \sqrt{5}+\sqrt{20}+\sqrt{45} \)?
Explanation opens after your attempt
A. \(6\sqrt{5}\)
Concept
\( \sqrt{20}=2\sqrt{5} \) and \( \sqrt{45}=3\sqrt{5} \). The total coefficient is (1+2+3=6), so the value is \(6\sqrt{5}\).
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 \(6\sqrt{5}\).
Exam Tip
\( \sqrt{20}=2\sqrt{5} \) और \( \sqrt{45}=3\sqrt{5} \)। कुल (1+2+3=6) से \(6\sqrt{5}\) मिलता है।
