Whakaoti i te 4^3-p=16

$$4 ^ { 3 - p } = 16$$

Whakaoti mō p

$$p=1$$

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

Whakamahia ngā ture taupū me ngā taupū kōaro hei whakaoti i te whārite.

$$4^{-p+3}=16$$

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

$$\log(4^{-p+3})=\log(16)$$

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

$$\left(-p+3\right)\log(4)=\log(16)$$

Whakawehea ngā taha e rua ki te \log(4).

$$-p+3=\frac{\log(16)}{\log(4)}$$

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

$$-p+3=\log_{4}\left(16\right)$$

Me tango 3 mai i ngā taha e rua o te whārite.

$$-p=2-3$$

Whakawehea ngā taha e rua ki te -1.

$$p=-\frac{1}{-1}$$
