Whakaoti i te 8(2/3)^-1(6/4)(4/2)^-7

$$8 ( \frac { 2 } { 3 } ) ^ { - 1 } ( \frac { 6 } { 4 } ) ( \frac { 4 } { 2 } ) ^ { - 7 }$$

Aromātai

$$\frac{9}{64}=0.140625$$

Ngā Upane Otinga

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

$$8\times \frac{3}{2}\times \frac{6}{4}\times \left(\frac{4}{2}\right)^{-7}$$

Whakareatia te 8 ki te \frac{3}{2}, ka 12.

$$12\times \frac{6}{4}\times \left(\frac{4}{2}\right)^{-7}$$

Whakahekea te hautanga \frac{6}{4} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$12\times \frac{3}{2}\times \left(\frac{4}{2}\right)^{-7}$$

Whakareatia te 12 ki te \frac{3}{2}, ka 18.

$$18\times \left(\frac{4}{2}\right)^{-7}$$

Whakawehea te 4 ki te 2, kia riro ko 2.

$$18\times 2^{-7}$$

Tātaihia te 2 mā te pū o -7, kia riro ko \frac{1}{128}.

$$18\times \frac{1}{128}$$

Whakareatia te 18 ki te \frac{1}{128}, ka \frac{9}{64}.

$$\frac{9}{64}$$

Tauwehe

$$\frac{3 ^ {2}}{2 ^ {6}} = 0.140625$$
