Выполним вычисления, представленные в задании:

$$5^2 = 5 \cdot 5 = 25$$
$$5^3 = 5 \cdot 5 \cdot 5 = 125$$
$$2.7^2 = 2.7 \cdot 2.7 = 7.29$$
$$2.7^3 = 2.7 \cdot 2.7 \cdot 2.7 = 19.683$$
$$(-3)^2 = (-3) \cdot (-3) = 9$$
$$(-3)^3 = (-3) \cdot (-3) \cdot (-3) = -27$$
$$(-0.2)^2 = (-0.2) \cdot (-0.2) = 0.04$$
$$(-0.2)^3 = (-0.2) \cdot (-0.2) \cdot (-0.2) = -0.008$$
$$(\frac{4}{9})^2 = \frac{4}{9} \cdot \frac{4}{9} = \frac{16}{81}$$
$$(\frac{4}{9})^3 = \frac{4}{9} \cdot \frac{4}{9} \cdot \frac{4}{9} = \frac{64}{729}$$
$$(1\frac{1}{6})^2 = (\frac{7}{6})^2 = \frac{7}{6} \cdot \frac{7}{6} = \frac{49}{36} = 1\frac{13}{36}$$
$$(1\frac{1}{6})^3 = (\frac{7}{6})^3 = \frac{7}{6} \cdot \frac{7}{6} \cdot \frac{7}{6} = \frac{343}{216} = 1\frac{127}{216}$$
