Whakaoti i te (7/8)^3div(8/7)^-3-(1/3-1)^0+3^-1

$$( \frac { 7 } { 8 } ) ^ { 3 } \div ( \frac { 8 } { 7 } ) ^ { - 3 } - ( \frac { 1 } { 3 } - 1 ) ^ { 0 } + 3 ^ { - 1 }$$

Aromātai

$$\frac{1}{3}\approx 0.333333333$$

Ngā Upane Otinga

Tātaihia te \frac{7}{8} mā te pū o 3, kia riro ko \frac{343}{512}.

$$\frac{\frac{343}{512}}{\left(\frac{8}{7}\right)^{-3}}-\left(\frac{1}{3}-1\right)^{0}+3^{-1}$$

Tātaihia te \frac{8}{7} mā te pū o -3, kia riro ko \frac{343}{512}.

$$\frac{\frac{343}{512}}{\frac{343}{512}}-\left(\frac{1}{3}-1\right)^{0}+3^{-1}$$

Whakawehea te \frac{343}{512} ki te \frac{343}{512}, kia riro ko 1.

$$1-\left(\frac{1}{3}-1\right)^{0}+3^{-1}$$

Tangohia te 1 i te \frac{1}{3}, ka -\frac{2}{3}.

$$1-\left(-\frac{2}{3}\right)^{0}+3^{-1}$$

Tātaihia te -\frac{2}{3} mā te pū o 0, kia riro ko 1.

$$1-1+3^{-1}$$

Tangohia te 1 i te 1, ka 0.

$$0+3^{-1}$$

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

$$0+\frac{1}{3}$$

Tāpirihia te 0 ki te \frac{1}{3}, ka \frac{1}{3}.

$$\frac{1}{3}$$

Tauwehe

$$\frac{1}{3} = 0.3333333333333333$$
