Question

Which choice is equivalent to the expression below? 25x - 4x + 2 O A. 5ſx O B. 3-5x + 2x O C. 157 O O D. 12x + 3√x

Answer 1

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}`
