7\times 10^{x}=119
Whakamahia ngā ture taupū me ngā taupū kōaro hei whakaoti i te whārite.
10^{x}=17
Whakawehea ngā taha e rua ki te 7.
\log(10^{x})=\log(17)
Tuhia te tau taupū kōaro o ngā taha e rua o te whārite.
x\log(10)=\log(17)
Ko te taupū kōaro o tētahi tau ka hīkina ki tētahi pū ko te pū whakarea ki te taupū kōaro o taua tau.
