Kua tāruatia ki te papatopenga
10^{-4}=39d
Hei whakarea i ngā pū o te pūtake kotahi, me tāpiri ō rātou taupū. Tāpiria te 1 me te -5 kia riro ai te -4.
\frac{1}{10000}=39d
Tātaihia te 10 mā te pū o -4, kia riro ko \frac{1}{10000}.
39d=\frac{1}{10000}
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
d=\frac{\frac{1}{10000}}{39}
Whakawehea ngā taha e rua ki te 39.
d=\frac{1}{10000\times 39}
Tuhia te \frac{\frac{1}{10000}}{39} hei hautanga kotahi.
d=\frac{1}{390000}
Whakareatia te 10000 ki te 39, ka 390000.
