\( \sqrt{20}+\sqrt{180}-\sqrt{80}-\sqrt{45} \) का मान क्या है?
What is the value of \( \sqrt{20}+\sqrt{180}-\sqrt{80}-\sqrt{45} \)?
Explanation opens after your attempt
A. (0)
Concept
They become \(2\sqrt{5},6\sqrt{5},4\sqrt{5},3\sqrt{5}\). Since (2+6-4-3=1), the result should be \( \sqrt{5} \).
Why this answer is correct
The correct answer is A. (0). They become \(2\sqrt{5},6\sqrt{5},4\sqrt{5},3\sqrt{5}\). Since (2+6-4-3=1), the result should be \( \sqrt{5} \).
Exam Tip
क्रमशः \(2\sqrt{5},6\sqrt{5},4\sqrt{5},3\sqrt{5}\) मिलते हैं। (2+6-4-3=1) से परिणाम \( \sqrt{5} \) होना चाहिए।
