8^{3}=25x
Hei whakarea i ngā pū o te pūtake kotahi, me tāpiri ō rātou taupū. Tāpiria te 1 me te 2 kia riro ai te 3.
512=25x
Tātaihia te 8 mā te pū o 3, kia riro ko 512.
25x=512
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x=\frac{512}{25}
Whakawehea ngā taha e rua ki te 25.
