Question

Which choice is equivalent to the product below when x is less then or equal to 0?

Answer 1

To solve this, let's first simplify, we have

`\begin{gathered} √(4x^2)*√(20x^2) \\ 2x*√(20)* x \\ 2x^2*√(4*5) \\ 2x^2*2*√(5) \\ 4x^2*√(5) \\ =4x^2√(5) \end{gathered}`

Hence the answer is option C
