Tohaina
Kua tāruatia ki te papatopenga
\log_{10}\left(\frac{10^{2}}{10^{7}}\right)
Hei whakarea i ngā pū o te pūtake kotahi, me tāpiri ō rātou taupū. Tāpiria te 5 me te -3 kia riro ai te 2.
\log_{10}\left(\frac{1}{10^{5}}\right)
Tuhia anō te 10^{7} hei 10^{2}\times 10^{5}. Me whakakore tahi te 10^{2} i te taurunga me te tauraro.
\log_{10}\left(\frac{1}{100000}\right)
Tātaihia te 10 mā te pū o 5, kia riro ko 100000.
-5
Ko te taupū kōaro 10 pūtake o \frac{1}{100000} ko -5.
