    does "and" mean add, multiply or are they two different problems?

    i assume when it says "simplify" it means to write in simplest radical form. in which case lagrange has it

    \[\sqrt{20}=\sqrt{4\times 10}=\sqrt{4}\times \sqrt{10}=2\sqrt{10}\]

    likewise \[\sqrt{200}=\sqrt{100\times 2}=\sqrt{100}\times \sqrt{2}=10\sqrt{2}\]

    \[\sqrt{40}= \sqrt{2 x 2 x 2 x 5} = 2 \sqrt{10}\] \[\sqrt{200}= \sqrt{2x2x2x5x5}\]
