Answer & Solution

Correct Answer

(C) 10

Step-by-step Solution

Detailed explanation

\((x-6 \sqrt{x}+9)-(2-\sqrt{3})|\sqrt{x}-3|-2 \sqrt{3}=0\) \(\Rightarrow|\sqrt{ x }-3|^2-(2-\sqrt{3})|\sqrt{ x }-3|-2 \sqrt{3}=0\) \(\Rightarrow|\sqrt{ x }-3|=2\) or \(|\sqrt{ x }-3|=-\sqrt{3}\) (not possible) \(\Rightarrow \sqrt{ x }=1\) or 5 \(\Rightarrow x=1\) or 5…
