Hei whakarea i ngā pū o te pūtake kotahi, me tāpiri ō rātou taupū. Tāpiria te -6 me te -6 kia riro ai te -12.

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

Tātaihia te 10 mā te pū o -12, kia riro ko \frac{1}{1000000000000}.

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

Whakareatia te 7 ki te \frac{1}{1000000000000}, ka \frac{7}{1000000000000}.

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

Whakareatia te \frac{7}{1000000000000} ki te 7, ka \frac{49}{1000000000000}.

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

Tātaihia te 10 mā te pū o -13, kia riro ko \frac{1}{10000000000000}.

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

Whakareatia te 49 ki te \frac{1}{10000000000000}, ka \frac{49}{10000000000000}.

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

Ko te maha noa iti rawa atu o 1000000000000 me 10000000000000 ko 10000000000000. Me tahuri \frac{49}{1000000000000} me \frac{49}{10000000000000} ki te hautau me te tautūnga 10000000000000.

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

Whakatauritea te \frac{490}{10000000000000} me te \frac{49}{10000000000000}.

$$\text{false}$$
