Answer 1

\[2x \sqrt{10xy}\]

Answer 2

How do you get that?

Answer 3

\[\sqrt{40x^3y}\]
\[\sqrt{4 \times 10 x^2 \times x \times y} \]

Answer 4

\[\sqrt{4} \sqrt{x^2} \sqrt{10xy}\]

\[2 \times x \times \sqrt{10xy}\]

\[2x \sqrt{10xy}\]

Answer 5

\[\sqrt{20 } * \sqrt{2} * \sqrt{x^2} * \sqrt{x} * \sqrt{y}\]
\[\sqrt{10} * \sqrt{2} * \sqrt{x} * \sqrt{x} * \sqrt{x} * \sqrt{y}\]
\[\sqrt{5} * \sqrt{2} * \sqrt{x} * \sqrt{x} * \sqrt{x} * \sqrt{y}\]
My final answer: \[5x^3y \sqrt{2}\]
