Question

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

Answer 1

SOLUTION

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

$\sqrt{2x}.\sqrt{x+3}$

Multiplying the root of the equation

$\begin{gathered} \sqrt{2x}.\sqrt{x+3} \\ \sqrt{2x(x+3)} \\ \sqrt{2x^2+6x} \end{gathered}$

Therefore the correct answer is

$\sqrt{2x^2+6x}$
