Whakaoti mō N_0
N_{0}=\frac{N}{e^{kt}}
Whakaoti mō N
N=N_{0}e^{kt}
Tohaina
Kua tāruatia ki te papatopenga
N_{0}e^{kt}=N
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
e^{kt}N_{0}=N
He hanga arowhānui tō te whārite.
\frac{e^{kt}N_{0}}{e^{kt}}=\frac{N}{e^{kt}}
Whakawehea ngā taha e rua ki te e^{kt}.
N_{0}=\frac{N}{e^{kt}}
Mā te whakawehe ki te e^{kt} ka wetekia te whakareanga ki te e^{kt}.
