Ответ:

Решение:

1. \( 5^2 = 25 \)
2. \( 5^3 = 125 \)
3. \( 2,7^2 = 7,29 \)
4. \( 2,7^3 = 19,683 \)
5. \( (-3)^2 = 9 \)
6. \( (-3)^3 = -27 \)
7. \( (-0,2)^2 = 0,04 \)
8. \( (-0,2)^3 = -0,008 \)
9. \( \left( \frac{4}{9} \right)^2 = \frac{16}{81} \)
10. \( \left( \frac{4}{9} \right)^3 = \frac{64}{729} \)
11. \( \left( 1 \frac{1}{6} \right)^2 = \left( \frac{7}{6} \right)^2 = \frac{49}{36} \)
12. \( \left( 1 \frac{1}{6} \right)^3 = \left( \frac{7}{6} \right)^3 = \frac{343}{216} \)
