Whakaoti i te sqrt[3]{646/125-11}-sqrt{01^-2}+sqrt[3]{8^2}

$$\sqrt[ 3 ] { \frac { 646 } { 125 } - 11 } - \sqrt { 01 ^ { - 2 } } + \sqrt[ 3 ] { 8 ^ { 2 } }$$

Aromātai

$$\frac{11}{5}=2.2$$

Ngā Upane Otinga

Tangohia te 11 i te \frac{646}{125}, ka -\frac{729}{125}.

$$\sqrt[3]{-\frac{729}{125}}-\sqrt{0\times 1^{-2}}+\sqrt[3]{8^{2}}$$

Tātaitia te \sqrt[3]{-\frac{729}{125}} kia tae ki -\frac{9}{5}.

$$-\frac{9}{5}-\sqrt{0\times 1^{-2}}+\sqrt[3]{8^{2}}$$

Tātaihia te 1 mā te pū o -2, kia riro ko 1.

$$-\frac{9}{5}-\sqrt{0\times 1}+\sqrt[3]{8^{2}}$$

Whakareatia te 0 ki te 1, ka 0.

$$-\frac{9}{5}-\sqrt{0}+\sqrt[3]{8^{2}}$$

Tātaitia te pūtakerua o 0 kia tae ki 0.

$$-\frac{9}{5}-0+\sqrt[3]{8^{2}}$$

Whakareatia te -1 ki te 0, ka 0.

$$-\frac{9}{5}+0+\sqrt[3]{8^{2}}$$

Tāpirihia te -\frac{9}{5} ki te 0, ka -\frac{9}{5}.

$$-\frac{9}{5}+\sqrt[3]{8^{2}}$$

Tātaihia te 8 mā te pū o 2, kia riro ko 64.

$$-\frac{9}{5}+\sqrt[3]{64}$$

Tātaitia te \sqrt[3]{64} kia tae ki 4.

$$-\frac{9}{5}+4$$

Tāpirihia te -\frac{9}{5} ki te 4, ka \frac{11}{5}.

$$\frac{11}{5}$$

Tauwehe

$$\frac{11}{5} = 2\frac{1}{5} = 2.2$$
