Whakaoti i te 16000/2*10^-5=2x10^11

$$\frac{ 16000 }{ 2 \times { 10 }^{ -5 } } = 2x { 10 }^{ 11 }$$

Whakaoti mō x

$$x=\frac{1}{250}=0.004$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

$$\frac{16000}{2\times \frac{1}{100000}}=2x\times 10^{11}$$

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

$$\frac{16000}{\frac{1}{50000}}=2x\times 10^{11}$$

Whakawehe 16000 ki te \frac{1}{50000} mā te whakarea 16000 ki te tau huripoki o \frac{1}{50000}.

$$16000\times 50000=2x\times 10^{11}$$

Whakareatia te 16000 ki te 50000, ka 800000000.

$$800000000=2x\times 10^{11}$$

Tātaihia te 10 mā te pū o 11, kia riro ko 100000000000.

$$800000000=2x\times 100000000000$$

Whakareatia te 2 ki te 100000000000, ka 200000000000.

$$800000000=200000000000x$$

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

$$200000000000x=800000000$$

Whakawehea ngā taha e rua ki te 200000000000.

$$x=\frac{800000000}{200000000000}$$

Whakahekea te hautanga \frac{800000000}{200000000000} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 800000000.

$$x=\frac{1}{250}$$
