Tohaina
Kua tāruatia ki te papatopenga
2.08\times 10^{-8}\times 9.5
Hei whakarea i ngā pū o te pūtake kotahi, me tāpiri ō rātou taupū. Tāpiria te -4 me te -4 kia riro ai te -8.
2.08\times \frac{1}{100000000}\times 9.5
Tātaihia te 10 mā te pū o -8, kia riro ko \frac{1}{100000000}.
\frac{13}{625000000}\times 9.5
Whakareatia te 2.08 ki te \frac{1}{100000000}, ka \frac{13}{625000000}.
\frac{247}{1250000000}
Whakareatia te \frac{13}{625000000} ki te 9.5, ka \frac{247}{1250000000}.
