Whakaoti i te 9=K(2)(3)^2/8

$$9 = \frac { K ( 2 ) ( 3 ) ^ { 2 } } { 8 }$$

Whakaoti mō K

$$K=4$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me whakarea ngā taha e rua ki te 8.

$$9\times 8=K\times 2\times 3^{2}$$

Whakareatia te 9 ki te 8, ka 72.

$$72=K\times 2\times 3^{2}$$

Tātaihia te 3 mā te pū o 2, kia riro ko 9.

$$72=K\times 2\times 9$$

Whakareatia te 2 ki te 9, ka 18.

$$72=K\times 18$$

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

$$K\times 18=72$$

Whakawehea ngā taha e rua ki te 18.

$$K=\frac{72}{18}$$

Whakawehea te 72 ki te 18, kia riro ko 4.

$$K=4$$
