Odpowiedź:
a)
2∛-1 - ∛-27 = -2 - (-3) = -2 + 3 = 1
b)
-∛-64/125 + ∛-0,125 = -(-4/5) + (-0,5) = 4/5 - 0,5 = 0,8 - 0,5 = 0,3
c)
∛-8/125 - ∛(-2 10/27) = -2/5 - ∛-64/27 = -2/5 + 4/3 = -6/15 + 20/15 = 14/15
d)
(∛-9 * ∛-9)/∛-3 = ∛81/∛-3 = ∛-27 = -3
e)
∛-16/(3∛2) - ∛-72/∛-9 = 1/3∛-8 - ∛-8 = -2/3 + 2 = 1 1/3
f)
∛-125/∛-1 + ∛-125/∛-1 = 5/1 + 5/1 = 5 + 5 = 10
