Passi tas-Soluzzjonijiet

Frazzjoni \frac{-2}{5} tista' tinkiteb mill-ġdid bħala -\frac{2}{5} bl-estrazzjoni tas-sinjal negattiv.

$$\frac{2\left(-\frac{2}{5}\right)}{\left(\frac{-3}{10}\right)^{4}}$$

Immultiplika 2 u -\frac{2}{5} biex tikseb -\frac{4}{5}.

$$\frac{-\frac{4}{5}}{\left(\frac{-3}{10}\right)^{4}}$$

Frazzjoni \frac{-3}{10} tista' tinkiteb mill-ġdid bħala -\frac{3}{10} bl-estrazzjoni tas-sinjal negattiv.

$$\frac{-\frac{4}{5}}{\left(-\frac{3}{10}\right)^{4}}$$

Ikkalkula -\frac{3}{10} bil-power ta' 4 u tikseb \frac{81}{10000}.

$$\frac{-\frac{4}{5}}{\frac{81}{10000}}$$

Iddividi -\frac{4}{5} b'\frac{81}{10000} billi timmultiplika -\frac{4}{5} bir-reċiproku ta' \frac{81}{10000}.

$$-\frac{4}{5}\times \frac{10000}{81}$$

Immultiplika -\frac{4}{5} u \frac{10000}{81} biex tikseb -\frac{8000}{81}.

$$-\frac{8000}{81}$$

Fattur

$$-\frac{8000}{81} = -98\frac{62}{81} = -98.76543209876543$$
