[tex]a) {2}^{5} = 2 \times 2 \times 2 \times 2 \times 2 = 32 \\ b) - 3 {}^{4} = - (3 \times 3 \times 3 \times 3) = - 81 \\ c)( \frac{2}{3} {)}^{ - 3} = (\frac{3}{2} {)}^{3} = \frac{3}{2} \times \frac{3}{2} \times \frac{3}{2} = \frac{27}{8} [/tex]

[tex]d) - 5 {}^{0} = - ( {5}^{0} ) = - 1 \\ e)(2 \frac{1}{2} {)}^{ - 2} = ( \frac{5}{2} {)}^{ - 2} = ( \frac{2}{5} {)}^{2} = \frac{2}{5} \times \frac{2}{5} = \frac{4}{25} \\ f)( - \frac{1}{3} {)}^{ - 3} = ( - 3 {)}^{3} = ( - 3) \times ( - 3) \times ( - 3) = - 27[/tex]

Odpowiedź:

a) = 32 b)= -81  c)= 0.07(407) d)= 0 e) = -5 f)= 1
