Odpowiedź:
[tex]14\frac{1}{6} \cdot 2\frac{6}{9} - 2\frac{1}{7} = \frac{85}{6} \cdot 2\frac{6}{9} - 2\frac{1}{7} = \frac{170}{9} - \frac{15}{7} = \frac{1055}{63} = 16\frac{47}{63}[/tex]
[tex](1\frac{1}{4})^4 = (\frac{5}{4})^4 = \frac{625}{256}[/tex]
[tex]1\frac{1}{5} + 8\frac{4}{6} \cdot 4\frac{7}{10} = \frac{6}{5} + \frac{52}{6} \cdot 2\frac{7}{5} = \frac{6}{5} + \frac{26}{3} \cdot 2\frac{7}{5} = \frac{6}{5} + \frac{364}{15} = \frac{382}{15}[/tex]
