Whakaoti i te 4^3(-12+2^3)/5(2)^2

$$\frac { 4 ^ { 3 } ( - 12 + 2 ^ { 3 } ) } { 5 ( 2 ) ^ { 2 } }$$

Aromātai

$$-\frac{64}{5}=-12.8$$

Ngā Upane Otinga

Tātaihia te 4 mā te pū o 3, kia riro ko 64.

$$\frac{64\left(-12+2^{3}\right)}{5\times 2^{2}}$$

Tātaihia te 2 mā te pū o 3, kia riro ko 8.

$$\frac{64\left(-12+8\right)}{5\times 2^{2}}$$

Tāpirihia te -12 ki te 8, ka -4.

$$\frac{64\left(-4\right)}{5\times 2^{2}}$$

Whakareatia te 64 ki te -4, ka -256.

$$\frac{-256}{5\times 2^{2}}$$

Tātaihia te 2 mā te pū o 2, kia riro ko 4.

$$\frac{-256}{5\times 4}$$

Whakareatia te 5 ki te 4, ka 20.

$$\frac{-256}{20}$$

Whakahekea te hautanga \frac{-256}{20} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$-\frac{64}{5}$$

Tauwehe

$$-\frac{64}{5} = -12\frac{4}{5} = -12.8$$
