Odpowiedź:
a)
√81 + 5 = 9 + 5 = 14
b)
∛1000 - 100 = 10 - 100 = -90
c)
4√1/121 = 4/11
d)
∛-27/18 = -3/18 = -1/6
e)
2∛125 - 3 = 2 * 5 - 3 = 10 - 3 = 7
f)
6/√144 + 1 = 6/12 + 1 = 1/2 + 1 = 1 1/2
g)
3∛-8/4 - 5 = 3 * (-2)/4 - 1 = -6/4 - 5 = -1 2/4 - 5 = -1 1/2 - 5 = -6 1/2
h)
√16 + ∛125 = 4 + 5 = 9
i)
√169 + √36 - √49 = 13 + 6 - 7 = 19 - 7 = 12
j)
∛1000 * √9 = 10 * 3 = 30
k)
√900 : ∛27 + √49 = 30 : 3 + 7 = 10 + 7 = 17
l)
3√36 + 5∛-64 = 3 * 6 + 5 * (-4) = 18 - 20 = -2
