e^{-9y}=11
Whakamahia ngā ture taupū me ngā taupū kōaro hei whakaoti i te whārite.
\log(e^{-9y})=\log(11)
Tuhia te tau taupū kōaro o ngā taha e rua o te whārite.
-9y\log(e)=\log(11)
Ko te taupū kōaro o tētahi tau ka hīkina ki tētahi pū ko te pū whakarea ki te taupū kōaro o taua tau.
-9y=\frac{\log(11)}{\log(e)}
Whakawehea ngā taha e rua ki te \log(e).
-9y=\log_{e}\left(11\right)
Mā te tikanga tātai huri pūtake \frac{\log(a)}{\log(b)}=\log_{b}\left(a\right).
y=\frac{\ln(11)}{-9}
Whakawehea ngā taha e rua ki te -9.
