Odpowiedź:
a) (40:-20)^5=(-2)^5= -32
b)
[tex](3 \frac{1}{7} ) ^{3} \div ( 2\frac{5}{14} ) ^{3} = ( \frac{22}{7} \div \frac{33}{14} ) ^{3} = ( \frac{22}{7} \times \frac{14}{33} ) ^{3} = ( \frac{2}{1} \times \frac{2}{3} )^{3} = ( \frac{4}{3} ) ^{3} = \frac{64}{27} = 2 \frac{10}{27} [/tex]
c)
(3,25:3,25)^8=(1)^8=1
d)
(0,729/0,081)^3 = 9^3 = 729
