a) $$10^3 = 10 \times 10 \times 10 = 1000$$
б) $$7^4 = 7 \times 7 \times 7 \times 7 = 2401$$
в) $$(-8)^4 = (-8) \times (-8) \times (-8) \times (-8) = 4096$$
г) $$3,2^2 = 3,2 \times 3,2 = 10,24$$
д) $$(-\frac{1}{3})^4 = (-\frac{1}{3}) \times (-\frac{1}{3}) \times (-\frac{1}{3}) \times (-\frac{1}{3}) = \frac{1}{81}$$
е) $$(1\frac{2}{3})^3 = (\frac{5}{3})^3 = \frac{5}{3} \times \frac{5}{3} \times \frac{5}{3} = \frac{125}{27} = 4\frac{17}{27}$$
