Question

8-11). Simplify the following radical expression as much as possible. Assume all variables represent positive numbers.

2 sqrt(45 x y^2)

Answer 1

\[2*\sqrt{45xy^2} = 2*\sqrt{45}*\sqrt{x}*\sqrt{y^2}= 2*\sqrt{9*5}*\sqrt{x}*y = 2y*\sqrt{9}*\sqrt{5x}=6y \sqrt{5x}\]

Answer 2

it looks like it is cut off. the answer is
\[6y \sqrt{5x}\]
