Kua tāruatia ki te papatopenga
1440\times \left(\frac{8}{3}\right)^{2x}=23
Whakamahia ngā ture taupū me ngā taupū kōaro hei whakaoti i te whārite.
\left(\frac{8}{3}\right)^{2x}=\frac{23}{1440}
Whakawehea ngā taha e rua ki te 1440.
\log(\left(\frac{8}{3}\right)^{2x})=\log(\frac{23}{1440})
Tuhia te tau taupū kōaro o ngā taha e rua o te whārite.
2x\log(\frac{8}{3})=\log(\frac{23}{1440})
Ko te taupū kōaro o tētahi tau ka hīkina ki tētahi pū ko te pū whakarea ki te taupū kōaro o taua tau.
2x=\frac{\log(\frac{23}{1440})}{\log(\frac{8}{3})}
Whakawehea ngā taha e rua ki te \log(\frac{8}{3}).
2x=\log_{\frac{8}{3}}\left(\frac{23}{1440}\right)
Mā te tikanga tātai huri pūtake \frac{\log(a)}{\log(b)}=\log_{b}\left(a\right).
x=\frac{\ln(\frac{23}{1440})}{2\ln(\frac{8}{3})}
Whakawehea ngā taha e rua ki te 2.
