sqrt=square root (by the way)

3-sqrt10 sqrt5+sqrt2

-------- * ----------

sqrt5-sqrt2 sqrt5+sqrt2

(3-sqrt10)(sqrt5+sqrt2)

= -----------------------

5-2

3sqrt5+3sqrt2-sqrt50-sqrt20

--------------------------

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

-------------- ?
