Answer 1

Se rationalizeaza numitorii.
5/5rad6 = 5rad6/(5×6) = rad6/6
1/5rad3 = rad3/(5×3) = rad3/15
3rad2/2rad3 = (3rad2×rad3)/(2×3) = rad6/2
2rad3/3rad2 = (2rad3×rad2)/(3×2) = rad6/3

rad6/6 + 2rad3 × (rad3/15 + rad6/2 - rad6/3) =
rad6/6 + 2/5 + 3rad2 - 2rad2 =
rad6/6 + 2/5 + rad2 =
(5rad6 + 12 + 30rad2)/30
