a) ∛ -8
---------------- = - 2/5
5
b) ∛ 64
-------------------- = - 4/3= - 1 i 1/3
∛- 27
c) √ 1 i 9/16 - ∛ 125/64=
√25/16 - 5/4=
5/4 - 5/4 = 0
d) 11 - 5
----------------------- = 1
12 - 6
e) ∛ 4 * 1/15 * 10 * 1/9 = ∛ 8/27 = 2/3
f) ∛ 2 i 1/2 * 1/20 = ∛ 5/2 * 1/20 = ∛ 1/8 = 1/2
g)∛ 8/10 : 1 i 9/16 = ∛ 8/10 * 16/25 = ∛64/125 = 4/5
h)∛ 5/6 : 1,44 = ∛ 5/6 : 1 i 22/50 = ∛5/6 * 50/72 = ∛ 125/216 = 5/6
