1) - 10Sqrt(100) + 6 Sqrt(847) + 2.* Sqrt(25) - 11Sqrt(252) = - 10 * 10 +  6Sgrt(121 * 7) + 2.9 * 5 - 11Sqrt(36 * 7) = - 100+ 6 * 11 Sqrt(7) +14.5 - 11 * 6 Sqrt(7) = - 100 + 66Sqrt(7) + 14.5 - 66Sqrt(7) = - 85.5
2) Sqrt(675) - 7Sqrt(507) - 3.4Sqrt(1875) + Sqrt(30000) =Sqrt(3 *225) - 7  Sqrt(3 * 169) - 3.4 * Sqrt(3 * 625) + Sqrt(3 * 10000) = 15Sqrt(3) - 7 * 13Sqrt(3) - 3.4 * 25Sqrt(3) + 100Sqrt(3) = 15Sqrt(3) - 91Sqrt(3) -  85Sqrt(3) + 100Sqrt(3) = - 61Sqrt(3)
