4\times 2^{x}=16
Whakamahia ngā ture taupū me ngā taupū kōaro hei whakaoti i te whārite.
2^{x}=4
Whakawehea ngā taha e rua ki te 4.
\log(2^{x})=\log(4)
Tuhia te tau taupū kōaro o ngā taha e rua o te whārite.
x\log(2)=\log(4)
Ko te taupū kōaro o tētahi tau ka hīkina ki tētahi pū ko te pū whakarea ki te taupū kōaro o taua tau.
x=\frac{\log(4)}{\log(2)}
Whakawehea ngā taha e rua ki te \log(2).
x=\log_{2}\left(4\right)
Mā te tikanga tātai huri pūtake \frac{\log(a)}{\log(b)}=\log_{b}\left(a\right).
