Whakaoti i te (20*10^4)=(24*10^-7)/x

$$( 20 \times 10 ^ { 4 } ) = \frac { ( 24 \times 10 ^ { - 7 } ) } { x }$$

Whakaoti mō x

$$x=\frac{3}{250000000000}=1.2 \cdot 10^{-11}$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tē taea kia ōrite te tāupe x ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te x.

$$20\times 10^{4}x=24\times 10^{-7}$$

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

$$20\times 10000x=24\times 10^{-7}$$

Whakareatia te 20 ki te 10000, ka 200000.

$$200000x=24\times 10^{-7}$$

Tātaihia te 10 mā te pū o -7, kia riro ko \frac{1}{10000000}.

$$200000x=24\times \frac{1}{10000000}$$

Whakareatia te 24 ki te \frac{1}{10000000}, ka \frac{3}{1250000}.

$$200000x=\frac{3}{1250000}$$

Whakawehea ngā taha e rua ki te 200000.

$$x=\frac{\frac{3}{1250000}}{200000}$$

Tuhia te \frac{\frac{3}{1250000}}{200000} hei hautanga kotahi.

$$x=\frac{3}{1250000\times 200000}$$

Whakareatia te 1250000 ki te 200000, ka 250000000000.

$$x=\frac{3}{250000000000}$$
