यदि \(x=\sqrt{5}+\sqrt{45}\) और \(y=\sqrt{80}\) हैं तो (x-y) का मान क्या है?
If \(x=\sqrt{5}+\sqrt{45}\) and \(y=\sqrt{80}\), what is the value of (x-y)?
Explanation opens after your attempt
A. (0)
Concept
\(x=\sqrt{5}+3\sqrt{5}=4\sqrt{5}\) and \(y=4\sqrt{5}\). Therefore (x-y=0).
Why this answer is correct
The correct answer is A. (0). \(x=\sqrt{5}+3\sqrt{5}=4\sqrt{5}\) and \(y=4\sqrt{5}\). Therefore (x-y=0).
Exam Tip
\(x=\sqrt{5}+3\sqrt{5}=4\sqrt{5}\) और \(y=4\sqrt{5}\) है। इसलिए (x-y=0) है।
