Given:


\sqrt[]{25x}-\sqrt[]{4x}+2\sqrt[]{x}

To simplify:

Step-by-step explanation:

On simplification we get,


\begin{gathered} \sqrt[]{25x}-\sqrt[]{4x}+2\sqrt[]{x}=\sqrt[]{5*5x}-\sqrt[]{2*2x}+2\sqrt[]{x} \\ =5\sqrt[]{x}-2\sqrt[]{x}+2\sqrt[]{x} \\ =5\sqrt[]{x} \end{gathered}

Final answer: Option A


5\sqrt[]{x}
