How would you solve this?

Answer 1

sqrt{90} + sqrt{250}

Answer 2

\[\sqrt{90}+\sqrt{250}\]
\[=\sqrt{9\times10}+\sqrt{25\times10}\]
\[=\sqrt{9}\times\sqrt{10}+\sqrt{25}\times\sqrt{10}\]

Answer 3

\[=(\sqrt9+\sqrt{25})\sqrt{10}\]

Answer 4

you have to simplify further

Answer 5

you can simplify the square roots in the brackets

Answer 6

Some how the correct answer is \[8\sqrt{10}\]

Answer 7

\[3\times3=9\]
so \(3=\sqrt9\)

Answer 8

\[5\times5=?\]

Answer 9

25

Answer 10

so do they expect you to add 5 +3 = 8 if so whats the formula they used behind that problem?

Answer 11

\[=(\sqrt{3\times3}+\sqrt{5\times5})\sqrt{10}\]
\[=(\sqrt{3^2}+\sqrt{5^2})\sqrt{10}\]
\[=(3+5)\sqrt{10}\]
