यदि \(A=\sqrt{125}+\sqrt{320}\) और \(B=13\sqrt{5}\) हैं तो कौन-सा कथन सही है?
If \(A=\sqrt{125}+\sqrt{320}\) and \(B=13\sqrt{5}\), which statement is correct?
Explanation opens after your attempt
A. (A=B)
Concept
\(\sqrt{125}=5\sqrt{5}\) and \(\sqrt{320}=8\sqrt{5}\), so \(A=13\sqrt{5}\). Hence (A=B).
Why this answer is correct
The correct answer is A. (A=B). \(\sqrt{125}=5\sqrt{5}\) and \(\sqrt{320}=8\sqrt{5}\), so \(A=13\sqrt{5}\). Hence (A=B).
Exam Tip
\(\sqrt{125}=5\sqrt{5}\) और \(\sqrt{320}=8\sqrt{5}\), इसलिए \(A=13\sqrt{5}\) है। अतः (A=B) है।
