यदि \(x=\sqrt{27}-\sqrt{12}\) तो (x) का मान क्या है?
If \(x=\sqrt{27}-\sqrt{12}\) then what is the value of (x)?
Explanation opens after your attempt
A. \(\sqrt{3}\)
Concept
\(\sqrt{27}=3\sqrt{3}\) and \(\sqrt{12}=2\sqrt{3}\), so \(x=\sqrt{3}\). Simplify surds first.
Why this answer is correct
The correct answer is A. \(\sqrt{3}\). \(\sqrt{27}=3\sqrt{3}\) and \(\sqrt{12}=2\sqrt{3}\), so \(x=\sqrt{3}\). Simplify surds first.
Exam Tip
\(\sqrt{27}=3\sqrt{3}\) और \(\sqrt{12}=2\sqrt{3}\) इसलिए \(x=\sqrt{3}\)। पहले मूलों को सरल करें।
