I have a problem that just kinda bugs me.
*= radical sign
5*6 + 2*10
is there anything that you can do with that??
$\displaystyle \sqrt{2}$ is a common factor
$\displaystyle \sqrt{ab} = \sqrt{a}\sqrt{b} \: , \: a,b \geq 0$
$\displaystyle 5\sqrt{6} = 5\sqrt{2}\sqrt{3}$
$\displaystyle 2\sqrt{10} = 2\sqrt{2}\sqrt{5}$
$\displaystyle
5\sqrt{2}\sqrt{3} + 2\sqrt{2}\sqrt{5} = \sqrt{2}(5\sqrt{3}+2\sqrt{5})$
But that seems pointless, better to leave it in the form you have it in unless it helps enormously to have the square root of 2 ready for further operation
