12767947514633659874603497973281=2^{x}
Tātaihia te 391 mā te pū o 12, kia riro ko 12767947514633659874603497973281.
2^{x}=12767947514633659874603497973281
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\log(2^{x})=\log(12767947514633659874603497973281)
Tuhia te tau taupū kōaro o ngā taha e rua o te whārite.
x\log(2)=\log(12767947514633659874603497973281)
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(12767947514633659874603497973281)}{\log(2)}
Whakawehea ngā taha e rua ki te \log(2).
x=\log_{2}\left(12767947514633659874603497973281\right)
Mā te tikanga tātai huri pūtake \frac{\log(a)}{\log(b)}=\log_{b}\left(a\right).
