Whakaoti i te {l}{2*10^-5*0.8}{*10^3}

$$\left. \begin{array} { l } { 2 \times 10 ^ { - 5 } \times 0.8 } \\ { \times 10 ^ { 3 } } \end{array} \right.$$

Ngā Upane Otinga

Hei whakarea i ngā pū o te pūtake kotahi, me tāpiri ō rātou taupū. Tāpiria te -5 me te 3 kia riro ai te -2.

$$2\times 10^{-2}\times 0.8$$

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

$$2\times \frac{1}{100}\times 0.8$$

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

$$\frac{1}{50}\times 0.8$$

Whakareatia te \frac{1}{50} ki te 0.8, ka \frac{2}{125}.

$$\frac{2}{125}$$

Tauwehe

$$\frac{2}{5 ^ {3}} = 0.016$$
