Passi tas-Soluzzjonijiet

Ikkalkula 10 bil-power ta' -4 u tikseb \frac{1}{10000}.

$$5\times \frac{1}{10000}-3\times 10^{-5}$$

Immultiplika 5 u \frac{1}{10000} biex tikseb \frac{1}{2000}.

$$\frac{1}{2000}-3\times 10^{-5}$$

Ikkalkula 10 bil-power ta' -5 u tikseb \frac{1}{100000}.

$$\frac{1}{2000}-3\times \frac{1}{100000}$$

Immultiplika 3 u \frac{1}{100000} biex tikseb \frac{3}{100000}.

$$\frac{1}{2000}-\frac{3}{100000}$$

Naqqas \frac{3}{100000} minn \frac{1}{2000} biex tikseb \frac{47}{100000}.

$$\frac{47}{100000}$$

Fattur

$$\frac{47}{2 ^ {5} \cdot 5 ^ {5}} = 0.00047$$
