Tohaina
Kua tāruatia ki te papatopenga
f\times 4=3\times 4^{3}
Whakaarohia te whārite tuatahi. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.
f\times 4=3\times 64
Tātaihia te 4 mā te pū o 3, kia riro ko 64.
f\times 4=192
Whakareatia te 3 ki te 64, ka 192.
f=\frac{192}{4}
Whakawehea ngā taha e rua ki te 4.
f=48
Whakawehea te 192 ki te 4, kia riro ko 48.
f=48 x=4
Kua oti te pūnaha te whakatau.
