Odpowiedź:
A.
[tex] \frac{3}{8} [/tex]
B.
[tex] - 2 \frac{2}{5} [/tex]
C.
[tex] - 200.08[/tex]
D.
[tex]-30[/tex]
Szczegółowe wyjaśnienie:
A.
[tex] - {( - \frac{1}{2} )}^{3} + {( \frac{1}{2}) }^{2} = - ( - \frac{1}{8} ) + \frac{1}{4} = \frac{ 1}{8} + \frac{2}{8} = \frac{3}{8} [/tex]
B.
[tex] {( \frac{4}{5} )}^{2} - \frac{ {4}^{2} }{5} + \frac{4}{ {5}^{2} } = \frac{16}{25} - \frac{16}{5} + \frac{4}{25} = \frac{20}{25} - \frac{16}{5} = \frac{4}{5} - \frac{16}{5} = - \frac{12}{5} = - 2 \frac{2}{5} [/tex]
C.
[tex]10 \times {( - 0.2)}^{3} - 0.2 \times {10}^{3} = 10 \times - 0.08 - 0.2 \times 1000 = - 0.8 - 200 = - 200.08[/tex]
D.
[tex] {6}^{2} \times \frac{1}{6} - { ( - \frac{1}{6} )}^{0} \times {( - 6)}^{2} = 6 - 1 \times 36 = - 30[/tex]
