Ngā Upane Otinga

Tātaihia te 2 mā te pū o -3, kia riro ko \frac{1}{8}.

$$\left(\frac{1}{\frac{1}{8}}-\frac{1}{2^{-1}}\right)^{-3}$$

Whakawehe 1 ki te \frac{1}{8} mā te whakarea 1 ki te tau huripoki o \frac{1}{8}.

$$\left(1\times 8-\frac{1}{2^{-1}}\right)^{-3}$$

Whakareatia te 1 ki te 8, ka 8.

$$\left(8-\frac{1}{2^{-1}}\right)^{-3}$$

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

$$\left(8-\frac{1}{\frac{1}{2}}\right)^{-3}$$

Whakawehe 1 ki te \frac{1}{2} mā te whakarea 1 ki te tau huripoki o \frac{1}{2}.

$$\left(8-1\times 2\right)^{-3}$$

Whakareatia te 1 ki te 2, ka 2.

$$\left(8-2\right)^{-3}$$

Tangohia te 2 i te 8, ka 6.

$$6^{-3}$$

Tātaihia te 6 mā te pū o -3, kia riro ko \frac{1}{216}.

$$\frac{1}{216}$$

Tauwehe

$$\frac{1}{2 ^ {3} \cdot 3 ^ {3}} = 0.004629629629629629$$
