MATH HELP PLEASE

Rewrite it with simplified radicals,

$5\sqrt{2} + 3\sqrt{2}$

They both have a radical of 2, so we can combine them to get $8\sqrt{2}$

Well we can simplify both of them starting with √50.

$\sqrt{50}$

$=\sqrt{2\cdot \:5^2}$

$=\sqrt{2}\sqrt{5^2}$

$=5\sqrt{2}$

$\sqrt{18}$

$=\sqrt{2\cdot \:3^2}$

$=\sqrt{2}\sqrt{3^2}$

$=3\sqrt{2}$

So adding $3\sqrt{2}+5\sqrt{2},$ you get $8\sqrt{2}$
