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

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

Aromātai

$$-\frac{250}{3}\approx -83.333333333$$

Ngā Upane Otinga

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

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

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

$$\frac{64\left(-12+4\right)}{\left(2\times 3\right)^{2}-5\times 2\times 3}+2$$

Tāpirihia te -12 ki te 4, ka -8.

$$\frac{64\left(-8\right)}{\left(2\times 3\right)^{2}-5\times 2\times 3}+2$$

Whakareatia te 64 ki te -8, ka -512.

$$\frac{-512}{\left(2\times 3\right)^{2}-5\times 2\times 3}+2$$

Whakareatia te 2 ki te 3, ka 6.

$$\frac{-512}{6^{2}-5\times 2\times 3}+2$$

Tātaihia te 6 mā te pū o 2, kia riro ko 36.

$$\frac{-512}{36-5\times 2\times 3}+2$$

Whakareatia te -5 ki te 2, ka -10.

$$\frac{-512}{36-10\times 3}+2$$

Whakareatia te -10 ki te 3, ka -30.

$$\frac{-512}{36-30}+2$$

Tangohia te 30 i te 36, ka 6.

$$\frac{-512}{6}+2$$

Whakahekea te hautanga \frac{-512}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$-\frac{256}{3}+2$$

Tāpirihia te -\frac{256}{3} ki te 2, ka -\frac{250}{3}.

$$-\frac{250}{3}$$

Tauwehe

$$-\frac{250}{3} = -83\frac{1}{3} = -83.33333333333333$$
