$4^{-3}=\dfrac{1}{4^3}=\dfrac{1}{64}=0,015625\\\\\\10^{-2}=\dfrac{1}{10^2}=\dfrac{1}{100}=0,01\\\\\\13^{-2}=\dfrac{1}{13^2}=\dfrac{1}{169}\\\\\\2,68^0=1\\\\\\(-5)^{-3}=\dfrac{1}{(-5)^3}=-\dfrac{1}{125}\\\\\\\Big(-\dfrac{5}{7}\Big)^{-1}=-\dfrac{7}{5}\\\\\\\Big(-\dfrac{1}{4}\Big)^{-3}=\dfrac{1}{(-4)^{-3}}=(-4)^3=-64\\\\\\\Big(-\dfrac{1}{12}\Big)^{-2}=\dfrac{1}{(-12)^{-2}}=12^2=144$
