a)
(0,25∛27 - 1/3⁴√256) * √[4(- 10)⁴] = (0,25 - 1/3 * 4) * 2√400 = (1/4 - 4/3) * 2 * 20 =
= (3/12 - 16/12) * 40 = - 13/12 * 40 = - 13/3 * 10 = - 130/3 = - 43 1/3 = - 43,(3)
b)
[√144 + 6∛(- 343)]/18 * (⁴√81 * 0,2√50) = [12 + 6 * (- 7)]/18 * (3 * 0,2 * 5√2) =
= (12 - 42)/18 * 3√2 = - 30/18 * 3√2 = - 30/6 * √2 = - 5√2
