Question

Which of the following is equivalent to the radical expression below when x≥0√2x • √x+3

Answer 1

Which of the following is equivalent to the radical expression below when x≥0

`√(2x).√(x+3)`

Multiplying the root of the equation

`\begin{gathered} √(2x).√(x+3) \\ √(2x(x+3)) \\ √(2x^2+6x) \end{gathered}`

Therefore the correct answer is

`√(2x^2+6x)`

Option C
