यदि \(x=3\sqrt{5}-\sqrt{45}\) है, तो (x) का मान क्या है?
If \(x=3\sqrt{5}-\sqrt{45}\), what is the value of (x)?
Explanation opens after your attempt
A. (0)
Concept
\(\sqrt{45}=3\sqrt{5}\), so \(3\sqrt{5}-3\sqrt{5}=0\). Simplify the radical first.
Why this answer is correct
The correct answer is A. (0). \(\sqrt{45}=3\sqrt{5}\), so \(3\sqrt{5}-3\sqrt{5}=0\). Simplify the radical first.
Exam Tip
\(\sqrt{45}=3\sqrt{5}\), इसलिए \(3\sqrt{5}-3\sqrt{5}=0\) है। पहले मूल को सरल करें।
