Passi tas-Soluzzjonijiet

Biex timmultiplika l-qawwa tal-istess bażi, żid l-esponenti tagħhom. Żid -3 u -3 biex tikseb -6.

$$9\times 10^{9}\times \frac{-2\times 10^{-6}\times 6}{0.4^{2}}$$

Ikkalkula 10 bil-power ta' 9 u tikseb 1000000000.

$$9\times 1000000000\times \frac{-2\times 10^{-6}\times 6}{0.4^{2}}$$

Immultiplika 9 u 1000000000 biex tikseb 9000000000.

$$9000000000\times \frac{-2\times 10^{-6}\times 6}{0.4^{2}}$$

Ikkalkula 10 bil-power ta' -6 u tikseb \frac{1}{1000000}.

$$9000000000\times \frac{-2\times \frac{1}{1000000}\times 6}{0.4^{2}}$$

Immultiplika -2 u \frac{1}{1000000} biex tikseb -\frac{1}{500000}.

$$9000000000\times \frac{-\frac{1}{500000}\times 6}{0.4^{2}}$$

Immultiplika -\frac{1}{500000} u 6 biex tikseb -\frac{3}{250000}.

$$9000000000\times \frac{-\frac{3}{250000}}{0.4^{2}}$$

Ikkalkula 0.4 bil-power ta' 2 u tikseb 0.16.

$$9000000000\times \frac{-\frac{3}{250000}}{0.16}$$

Esprimi \frac{-\frac{3}{250000}}{0.16} bħala frazzjoni waħda.

$$9000000000\times \frac{-3}{250000\times 0.16}$$

Immultiplika 250000 u 0.16 biex tikseb 40000.

$$9000000000\times \frac{-3}{40000}$$

Frazzjoni \frac{-3}{40000} tista' tinkiteb mill-ġdid bħala -\frac{3}{40000} bl-estrazzjoni tas-sinjal negattiv.

$$9000000000\left(-\frac{3}{40000}\right)$$

Immultiplika 9000000000 u -\frac{3}{40000} biex tikseb -675000.
