Whakaoti i te 1600/10^-5*2=10^4*2x

$$\frac { 1600 } { 10 ^ { - 5 } \times 2 } = 10 ^ { 4 } \times 2 x$$

Whakaoti mō x

$$x=4000$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tātaihia te 10 mā te pū o -5, kia riro ko \frac{1}{100000}.

$$\frac{1600}{\frac{1}{100000}\times 2}=10^{4}\times 2x$$

Whakareatia te \frac{1}{100000} ki te 2, ka \frac{1}{50000}.

$$\frac{1600}{\frac{1}{50000}}=10^{4}\times 2x$$

Whakawehe 1600 ki te \frac{1}{50000} mā te whakarea 1600 ki te tau huripoki o \frac{1}{50000}.

$$1600\times 50000=10^{4}\times 2x$$

Whakareatia te 1600 ki te 50000, ka 80000000.

$$80000000=10^{4}\times 2x$$

Tātaihia te 10 mā te pū o 4, kia riro ko 10000.

$$80000000=10000\times 2x$$

Whakareatia te 10000 ki te 2, ka 20000.

$$80000000=20000x$$

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

$$20000x=80000000$$

Whakawehea ngā taha e rua ki te 20000.

$$x=\frac{80000000}{20000}$$

Whakawehea te 80000000 ki te 20000, kia riro ko 4000.

$$x=4000$$
