Odpowiedź:
a) [tex](\frac{2}{5})^{2} = \frac{4}{25}[/tex]
[tex]\frac{2^{2}}{5} = \frac{4}{5}[/tex]
[tex]\frac{4}{25} < \frac{4}{5}[/tex]
[tex](\frac{2}{5})^{2} < \frac{2^{2}}{5}[/tex]
b) [tex](\frac{1}{7})^{^7} < \frac{2}{7^{7}}[/tex]
c) [tex]\frac{-2^{6}}{3^{6}} < (-\frac{2}{3})^{6}[/tex]
d) [tex]\frac{-2^{9}}{-9^{9}} > (-\frac{2}{9})^{9}[/tex]
