Whakaoti i te 2+2=3^x

$$2 + 2 = 3 ^ { x }$$

Whakaoti mō x

$$x=2\log_{3}\left(2\right)\approx 1.261859507$$

Ngā Upane e Whakamahi ana i te Tautuhinga o te Taupū Kōaro

Tāpirihia te 2 ki te 2, ka 4.

$$4=3^{x}$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$3^{x}=4$$

Tuhia te tau taupū kōaro o ngā taha e rua o te whārite.

$$\log(3^{x})=\log(4)$$

Ko te taupū kōaro o tētahi tau ka hīkina ki tētahi pū ko te pū whakarea ki te taupū kōaro o taua tau.

$$x\log(3)=\log(4)$$

Whakawehea ngā taha e rua ki te \log(3).

$$x=\frac{\log(4)}{\log(3)}$$

Mā te tikanga tātai huri pūtake \frac{\log(a)}{\log(b)}=\log_{b}\left(a\right).

$$x=\log_{3}\left(4\right)$$

Whakaoti mō x (complex solution)

$$x=\frac{2\pi n_{1}i}{\ln(3)}+2\log_{3}\left(2\right)$$

$$n_{1}\in \mathrm{Z}$$
