Whakaoti i te 0.1*10=x*2*10^-2

$$0.1 \times 10=x \times 2 \times { 10 }^{ -2 }$$

Whakaoti mō x

$$x=50$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakareatia te 0.1 ki te 10, ka 1.

$$1=x\times 2\times 10^{-2}$$

Tātaihia te 10 mā te pū o -2, kia riro ko \frac{1}{100}.

$$1=x\times 2\times \frac{1}{100}$$

Whakareatia te 2 ki te \frac{1}{100}, ka \frac{1}{50}.

$$1=x\times \frac{1}{50}$$

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

$$x\times \frac{1}{50}=1$$

Me whakarea ngā taha e rua ki te 50, te tau utu o \frac{1}{50}.

$$x=1\times 50$$

Whakareatia te 1 ki te 50, ka 50.

$$x=50$$
