zad 5
∛(10² + 3² + 2⁴) + √8 * √1,5 * √3 = ∛(100 + 9 + 16) + √(8 * 1,5 * 3) =
= ∛125 + √36 = 5 + 6 = 11
zad 6
[√(2 34/81 : ∛(343/512) + √(7 1/9)] * ∛(5 104/125) =
= [√(196/81) : 7/8 + √(64/9) * ∛(729/125) = (14/9 * 8/7 + 8/9) * 9/5 =
= (2/9 * 8 + 8/9) * 9/5 = (16/9 + 8/9) * 9/5 = 24/9 * 9/5 = 24/5 = 4 4/5
