Odpowiedź:
a)
[tex](1 \frac{3}{4} ) ^{2} = 1 \frac{3}{4} \times 1 \frac{3}{4} = \frac{7}{4} \times \frac{7}{4} = \frac{49}{16} = 3 \frac{1}{16} [/tex]
b)
[tex]( - 1 \frac{2}{5} )^{3} = - 1 \frac{2}{5} \times - 1 \frac{2}{5} \times - 1 \frac{2}{5} = - \frac{7}{5} \times - \frac{7}{5} \times - \frac{7}{5} = - \frac{343}{125} = - 3 \frac{93}{125} [/tex]
c)
[tex]( - 3 \frac{4}{7} ) ^{2} = - 3 \frac{4}{7} \times ( - 3 \frac{4}{7} ) = - \frac{25}{7} \times (- \frac{25}{7}) = \frac{625}{49} = 13 \frac{37}{49} [/tex]
d)
[tex](2 \frac{1}{3} ) ^ {3} = 2 \frac{1}{3} \times 2 \frac{1}{2} \times 2\frac{1}{3} = \frac{7}{3} \times \frac{7}{3} \times \frac{7}{3} = \frac{343}{27} = 12 \frac{19}{27} [/tex]
