Tohaina
Kua tāruatia ki te papatopenga
9\times 12^{n}=88
Whakamahia ngā ture taupū me ngā taupū kōaro hei whakaoti i te whārite.
12^{n}=\frac{88}{9}
Whakawehea ngā taha e rua ki te 9.
\log(12^{n})=\log(\frac{88}{9})
Tuhia te tau taupū kōaro o ngā taha e rua o te whārite.
n\log(12)=\log(\frac{88}{9})
Ko te taupū kōaro o tētahi tau ka hīkina ki tētahi pū ko te pū whakarea ki te taupū kōaro o taua tau.
n=\frac{\log(\frac{88}{9})}{\log(12)}
Whakawehea ngā taha e rua ki te \log(12).
n=\log_{12}\left(\frac{88}{9}\right)
Mā te tikanga tātai huri pūtake \frac{\log(a)}{\log(b)}=\log_{b}\left(a\right).
