Whakaoti i te 8^-1*5^-1/2^-4

$$\frac { 8 ^ { - 1 } \times 5 ^ { - 1 } } { 2 ^ { - 4 } }$$

Aromātai

$$\frac{2}{5}=0.4$$

Ngā Upane Otinga

Tātaihia te 8 mā te pū o -1, kia riro ko \frac{1}{8}.

$$\frac{\frac{1}{8}\times 5^{-1}}{2^{-4}}$$

Tātaihia te 5 mā te pū o -1, kia riro ko \frac{1}{5}.

$$\frac{\frac{1}{8}\times \frac{1}{5}}{2^{-4}}$$

Whakareatia te \frac{1}{8} ki te \frac{1}{5}, ka \frac{1}{40}.

$$\frac{\frac{1}{40}}{2^{-4}}$$

Tātaihia te 2 mā te pū o -4, kia riro ko \frac{1}{16}.

$$\frac{\frac{1}{40}}{\frac{1}{16}}$$

Whakawehe \frac{1}{40} ki te \frac{1}{16} mā te whakarea \frac{1}{40} ki te tau huripoki o \frac{1}{16}.

$$\frac{1}{40}\times 16$$

Whakareatia te \frac{1}{40} ki te 16, ka \frac{2}{5}.

$$\frac{2}{5}$$

Tauwehe

$$\frac{2}{5} = 0.4$$
