Whakaoti mō P
\left\{\begin{matrix}P=\frac{O}{t}\text{, }&t\neq 0\\P\in \mathrm{R}\text{, }&O=0\text{ and }t=0\end{matrix}\right.
Whakaoti mō O
O=Pt
Tohaina
Kua tāruatia ki te papatopenga
Pt=O
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
tP=O
He hanga arowhānui tō te whārite.
\frac{tP}{t}=\frac{O}{t}
Whakawehea ngā taha e rua ki te t.
P=\frac{O}{t}
Mā te whakawehe ki te t ka wetekia te whakareanga ki te t.
Ngā Tauira
