Izračunajte koliko je -8 na 10 da biste dobili \frac{1}{100000000}.

$$\frac{5\left(17-\frac{1}{100000000}\right)}{2\times 10^{-4}}$$

Oduzmite \frac{1}{100000000} od 17 da biste dobili \frac{1699999999}{100000000}.

$$\frac{5\times \frac{1699999999}{100000000}}{2\times 10^{-4}}$$

Pomnožite 5 i \frac{1699999999}{100000000} da biste dobili \frac{1699999999}{20000000}.

$$\frac{\frac{1699999999}{20000000}}{2\times 10^{-4}}$$

Izračunajte koliko je -4 na 10 da biste dobili \frac{1}{10000}.

$$\frac{\frac{1699999999}{20000000}}{2\times \frac{1}{10000}}$$

Pomnožite 2 i \frac{1}{10000} da biste dobili \frac{1}{5000}.

$$\frac{\frac{1699999999}{20000000}}{\frac{1}{5000}}$$

Podijelite \frac{1699999999}{20000000} s \frac{1}{5000} tako da pomnožite \frac{1699999999}{20000000} s brojem recipročnim broju \frac{1}{5000}.

$$\frac{1699999999}{20000000}\times 5000$$

Pomnožite \frac{1699999999}{20000000} i 5000 da biste dobili \frac{1699999999}{4000}.

$$\frac{1699999999}{4000}$$

Faktor

$$\frac{2957 \cdot 574907}{2 ^ {5} \cdot 5 ^ {3}} = 424999\frac{3999}{4000} = 424999,99975$$
