Da biste pomnožili potencije s istom bazom, zbrojite eksponente. Dodajte -6 i -6 da biste dobili -12.

$$7\times 10^{-12}\times 7=49\times 10^{-13}$$

Izračunajte koliko je -12 na 10 da biste dobili \frac{1}{1000000000000}.

$$7\times \frac{1}{1000000000000}\times 7=49\times 10^{-13}$$

Pomnožite 7 i \frac{1}{1000000000000} da biste dobili \frac{7}{1000000000000}.

$$\frac{7}{1000000000000}\times 7=49\times 10^{-13}$$

Pomnožite \frac{7}{1000000000000} i 7 da biste dobili \frac{49}{1000000000000}.

$$\frac{49}{1000000000000}=49\times 10^{-13}$$

Izračunajte koliko je -13 na 10 da biste dobili \frac{1}{10000000000000}.

$$\frac{49}{1000000000000}=49\times \frac{1}{10000000000000}$$

Pomnožite 49 i \frac{1}{10000000000000} da biste dobili \frac{49}{10000000000000}.

$$\frac{49}{1000000000000}=\frac{49}{10000000000000}$$

Najmanji zajednički višekratnik brojeva 1000000000000 i 10000000000000 je 10000000000000. Pretvorite \frac{49}{1000000000000} i \frac{49}{10000000000000} u razlomak s nazivnikom 10000000000000.

$$\frac{490}{10000000000000}=\frac{49}{10000000000000}$$

Usporedite \frac{490}{10000000000000} i \frac{49}{10000000000000}.

$$\text{false}$$
