Whakaoti i te (x-3*10^2*4)div(9*10^2*8)

$$(x-3 \times { 10 }^{ 2 \times 4 } ) \div (9 \times { 10 }^{ 2 \times 8 } )$$

Aromātai

$$\frac{x-300000000}{90000000000000000}$$

Ngā Upane Otinga

Whakareatia te 2 ki te 4, ka 8.

$$\frac{x-3\times 10^{8}}{9\times 10^{2\times 8}}$$

Tātaihia te 10 mā te pū o 8, kia riro ko 100000000.

$$\frac{x-3\times 100000000}{9\times 10^{2\times 8}}$$

Whakareatia te 3 ki te 100000000, ka 300000000.

$$\frac{x-300000000}{9\times 10^{2\times 8}}$$

Whakareatia te 2 ki te 8, ka 16.

$$\frac{x-300000000}{9\times 10^{16}}$$

Tātaihia te 10 mā te pū o 16, kia riro ko 10000000000000000.

$$\frac{x-300000000}{9\times 10000000000000000}$$

Whakareatia te 9 ki te 10000000000000000, ka 90000000000000000.

$$\frac{x-300000000}{90000000000000000}$$
