a) (3√50+2√8-√32): √2 = (3 * 7.07 + 2 * 2.83 – 5.66) : 1.41 = (21.21 + 5.66 – 5.66) : 1.41 = 21.21 : 1.41 = 15.04
c) (8∛-16+2∛-54-3∛-128): ∛-2 = (8 * -2.52 + 2 * -3.69 – 3 * -5.04) : -1.27 = (-20.16 + (-7.38) - (-15.12)) : -1.27 =(-20.16 – 7.38 + 15.12) : -1.27 = -12.42 : -1.27 = 9.78
d) (4∛625-3∛40+∛320): ∛5 = (4 * 8.55 – 3 * 3.42 + 6.87) : 1.70 = (34.2 – 10.26 + 6.87) :1.70=30.81 : 1.70 = 18.12
