Whakaoti i te (138*10^8)*(54*10^-12)

$$(138 \times { 10 }^{ 8 } ) \times (54 \times { 10 }^{ -12 } )$$

Aromātai

$$\frac{1863}{2500}=0.7452$$

Ngā Upane Otinga

Hei whakarea i ngā pū o te pūtake kotahi, me tāpiri ō rātou taupū. Tāpiria te 8 me te -12 kia riro ai te -4.

$$138\times 10^{-4}\times 54$$

Tātaihia te 10 mā te pū o -4, kia riro ko \frac{1}{10000}.

$$138\times \frac{1}{10000}\times 54$$

Whakareatia te 138 ki te \frac{1}{10000}, ka \frac{69}{5000}.

$$\frac{69}{5000}\times 54$$

Whakareatia te \frac{69}{5000} ki te 54, ka \frac{1863}{2500}.

$$\frac{1863}{2500}$$

Tauwehe

$$\frac{3 ^ {4} \cdot 23}{2 ^ {2} \cdot 5 ^ {4}} = 0.7452$$
