Passi tas-Soluzzjonijiet

Biex timmultiplika l-qawwa tal-istess bażi, żid l-esponenti tagħhom. Żid -6 u -6 biex tikseb -12.

$$9\times 10^{9}\times \frac{-5\times 10^{-12}\left(-4\right)}{0.2^{2}}$$

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

$$9\times 1000000000\times \frac{-5\times 10^{-12}\left(-4\right)}{0.2^{2}}$$

Immultiplika 9 u 1000000000 biex tikseb 9000000000.

$$9000000000\times \frac{-5\times 10^{-12}\left(-4\right)}{0.2^{2}}$$

Ikkalkula 10 bil-power ta' -12 u tikseb \frac{1}{1000000000000}.

$$9000000000\times \frac{-5\times \frac{1}{1000000000000}\left(-4\right)}{0.2^{2}}$$

Immultiplika -5 u \frac{1}{1000000000000} biex tikseb -\frac{1}{200000000000}.

$$9000000000\times \frac{-\frac{1}{200000000000}\left(-4\right)}{0.2^{2}}$$

Immultiplika -\frac{1}{200000000000} u -4 biex tikseb \frac{1}{50000000000}.

$$9000000000\times \frac{\frac{1}{50000000000}}{0.2^{2}}$$

Ikkalkula 0.2 bil-power ta' 2 u tikseb 0.04.

$$9000000000\times \frac{\frac{1}{50000000000}}{0.04}$$

Esprimi \frac{\frac{1}{50000000000}}{0.04} bħala frazzjoni waħda.

$$9000000000\times \frac{1}{50000000000\times 0.04}$$

Immultiplika 50000000000 u 0.04 biex tikseb 2000000000.

$$9000000000\times \frac{1}{2000000000}$$

Immultiplika 9000000000 u \frac{1}{2000000000} biex tikseb \frac{9}{2}.

$$\frac{9}{2}$$

Fattur

$$\frac{3 ^ {2}}{2} = 4\frac{1}{2} = 4.5$$
