Whakaoti i te {left(-2/3right)}^3{left(2/3right)}^-2{left(-2/3right)}^01

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

Aromātai

$$-\frac{2}{3}\approx -0.666666667$$

Ngā Upane Otinga

Hei whakarea i ngā pū o te pūtake kotahi, me tāpiri ō rātou taupū. Tāpiria te 3 me te 0 kia riro ai te 3.

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

Tātaihia te -\frac{2}{3} mā te pū o 3, kia riro ko -\frac{8}{27}.

$$-\frac{8}{27}\times \left(\frac{2}{3}\right)^{-2}$$

Tātaihia te \frac{2}{3} mā te pū o -2, kia riro ko \frac{9}{4}.

$$-\frac{8}{27}\times \frac{9}{4}$$

Whakareatia te -\frac{8}{27} ki te \frac{9}{4}, ka -\frac{2}{3}.

$$-\frac{2}{3}$$

Tauwehe

$$-\frac{2}{3} = -0.6666666666666666$$
