Whakaoti i te 1((7*10^-1)(3*10^-1)/10^2)

$$1( \frac{ (7 \times { 10 }^{ -1 } )(3 \times { 10 }^{ -1 } ) }{ { 10 }^{ 2 } } )$$

Aromātai

$$\frac{21}{10000}=0.0021$$

Ngā Upane Otinga

Hei whakarea i ngā pū o te pūtake kotahi, me tāpiri ō rātou taupū. Tāpiria te -1 me te -1 kia riro ai te -2.

$$1\times \frac{7\times 10^{-2}\times 3}{10^{2}}$$

Hei whakawehe i ngā pū o te pūtake kotahi, tangohia te taupū o te taurunga i te taupū o te tauraro.

$$1\times \frac{3\times 7}{10^{4}}$$

Whakareatia te 3 ki te 7, ka 21.

$$1\times \frac{21}{10^{4}}$$

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

$$1\times \frac{21}{10000}$$

Whakareatia te 1 ki te \frac{21}{10000}, ka \frac{21}{10000}.

$$\frac{21}{10000}$$

Tauwehe

$$\frac{3 \cdot 7}{2 ^ {4} \cdot 5 ^ {4}} = 0.0021$$
