Whakaoti i te (1/2^-3-1/2^-1)

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

Aromātai

$$6$$

Ngā Upane Otinga

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

$$\frac{1}{\frac{1}{8}}-\frac{1}{2^{-1}}$$

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

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

Whakareatia te 1 ki te 8, ka 8.

$$8-\frac{1}{2^{-1}}$$

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

$$8-\frac{1}{\frac{1}{2}}$$

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

$$8-1\times 2$$

Whakareatia te 1 ki te 2, ka 2.

$$8-2$$

Tangohia te 2 i te 8, ka 6.

$$6$$

Tauwehe

$$2\times 3$$
