If its possible, could you please do this on paint or something for me, and upload it so I can see how exactly you solved this, because explaining over Jiskha, will probably be hard for me to understand as I will not be able to visualize certain steps.

√6(2√6  √5)
To multiply two radicals, just keep the radical sign and then multiply the two numbers inside.
e.g. √5 x √7 = √35
and then of course √6 x √6 = √36 = 6
when you multiply a square root by itself, you get that number
√13 x √13 = 13
so back to our question, let's just expand it
= 2√36  √30
= 2(6)  √30
= 12  √30
