Oblicz
3-^4
(1/6)-^2
(4/3)-^3
(1 4/5)-^2
(-0, 1)-^3
-0, 2-^3

irenas $3^{-4}=\frac{1}{81}$

$(\frac{1}{6})^{-2}=6^2=36$

$(\frac{4}{3})^{-3}=\frac{27}{64}$

$(1\frac{4}{5})^{-2}=(\frac{9}{5})^{-2}=\frac{81}{25}$

$(-0,1)^{-3}=-1000$

$-0,2^{-3}=-5^3=-125$

Alexsandrixonka $3^{-4}=(\frac{1}{3})^{4}=\frac{1}{3}*\frac{1}{3}*\frac{1}{3}*\frac{1}{3}=\frac{1}{81}\\\\(\frac{1}{6})^{-2}=6^{2}=6*6=36\\\\(\frac{4}{3})^{-3}=(\frac{3}{4})^{3}=\frac{3}{4}*\frac{3}{4}*\frac{3}{4}=\frac{27}{64}$

$(1\frac{4}{5})^{-2}=(\frac{9}{5})^{-2}=(\frac{5}{9})^{2}=\frac{5}{9}*\frac{5}{9}=\frac{25}{81}\\\\(-0,1)^{-3}=(-\frac{1}{10})^{-3}=(-10)^{3}=(-10)*(-10)*(-10)=-1000\\\\-0,2^{-3}=-(\frac{1}{5})^{-3}=-5^{3}=-125$
