Whakaoti i te {left(2/3right)}^3-1/9sqrt[3]{8/27}

$${ \left( \frac{ 2 }{ 3 } \right) }^{ 3 } - \frac{ 1 }{ 9 } \sqrt[ 3 ]{ \frac{ 8 }{ 27 } }$$

Aromātai

$$\frac{2}{9}\approx 0.222222222$$

Ngā Upane Otinga

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

$$\frac{8}{27}-\frac{1}{9}\sqrt[3]{\frac{8}{27}}$$

Tātaitia te \sqrt[3]{\frac{8}{27}} kia tae ki \frac{2}{3}.

$$\frac{8}{27}-\frac{1}{9}\times \frac{2}{3}$$

Whakareatia te -\frac{1}{9} ki te \frac{2}{3}, ka -\frac{2}{27}.

$$\frac{8}{27}-\frac{2}{27}$$

Tangohia te \frac{2}{27} i te \frac{8}{27}, ka \frac{2}{9}.

$$\frac{2}{9}$$

Tauwehe

$$\frac{2}{3 ^ {2}} = 0.2222222222222222$$
