• a) $$3^4 = 3 \times 3 \times 3 \times 3 = 81$$
• б) $$2^5 = 2 \times 2 \times 2 \times 2 \times 2 = 32$$
• в) $$(-1.2)^2 = (-1.2) \times (-1.2) = 1.44$$
• г) $$\left(\frac{2}{3}\right)^3 = \frac{2}{3} \times \frac{2}{3} \times \frac{2}{3} = \frac{8}{27}$$
• д) $$\left(-1 \frac{1}{2}\right)^4 = \left(-\frac{3}{2}\right)^4 = \frac{(-3)^4}{2^4} = \frac{81}{16} = 5 \frac{1}{16} = 5.0625$$
• e) $$\left(-3 \frac{1}{4}\right)^2 = \left(-\frac{13}{4}\right)^2 = \frac{(-13)^2}{4^2} = \frac{169}{16} = 10 \frac{9}{16} = 10.5625$$
