Can someone please check my work on this problem? For some reason, I get the feeling that I did it wrong.
sqrt=square root (by the way)
3sqrt10 sqrt5+sqrt2
 * 
sqrt5sqrt2 sqrt5+sqrt2
(3sqrt10)(sqrt5+sqrt2)
= 
52
3sqrt5+3sqrt2sqrt50sqrt20

Thanks in advance!
Yes, however, I would simplify
sqrt 12= 2 sqrt3
sqrt 50= 5sqrt2
sqrt 20= 2sqrt5
do that , and you can simplify more.
I don't think I have to know the sqrt12...?
So the answer would be 2sqrt2+1sqrt5
 ?
