\(\sqrt{500}-\sqrt{320}+\sqrt{180}\) का सरल रूप क्या है?
What is the simplified form of \(\sqrt{500}-\sqrt{320}+\sqrt{180}\)?
Explanation opens after your attempt
A. \(12\sqrt{5}\)
Concept
\(\sqrt{500}=10\sqrt{5}\), \(\sqrt{320}=8\sqrt{5}\), and \(\sqrt{180}=6\sqrt{5}\). So the result is \(10\sqrt{5}-8\sqrt{5}+6\sqrt{5}=8\sqrt{5}\).
Why this answer is correct
The correct answer is A. \(12\sqrt{5}\). \(\sqrt{500}=10\sqrt{5}\), \(\sqrt{320}=8\sqrt{5}\), and \(\sqrt{180}=6\sqrt{5}\). So the result is \(10\sqrt{5}-8\sqrt{5}+6\sqrt{5}=8\sqrt{5}\).
Exam Tip
\(\sqrt{500}=10\sqrt{5}\), \(\sqrt{320}=8\sqrt{5}\) और \(\sqrt{180}=6\sqrt{5}\) है। इसलिए परिणाम \(8\sqrt{5}\) नहीं, \(10\sqrt{5}-8\sqrt{5}+6\sqrt{5}=8\sqrt{5}\) है।
