Whakaoti i te -2^3+1/3*(2017+3)^0-(1/3)^-2

$$- 2 ^ { 3 } + \frac { 1 } { 3 } \times ( 2017 + 3 ) ^ { 0 } - ( \frac { 1 } { 3 } ) ^ { - 2 }$$

Aromātai

$$-\frac{50}{3}\approx -16.666666667$$

Ngā Upane Otinga

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

$$-8+\frac{1}{3}\left(2017+3\right)^{0}-\left(\frac{1}{3}\right)^{-2}$$

Tāpirihia te 2017 ki te 3, ka 2020.

$$-8+\frac{1}{3}\times 2020^{0}-\left(\frac{1}{3}\right)^{-2}$$

Tātaihia te 2020 mā te pū o 0, kia riro ko 1.

$$-8+\frac{1}{3}\times 1-\left(\frac{1}{3}\right)^{-2}$$

Whakareatia te \frac{1}{3} ki te 1, ka \frac{1}{3}.

$$-8+\frac{1}{3}-\left(\frac{1}{3}\right)^{-2}$$

Tāpirihia te -8 ki te \frac{1}{3}, ka -\frac{23}{3}.

$$-\frac{23}{3}-\left(\frac{1}{3}\right)^{-2}$$

Tātaihia te \frac{1}{3} mā te pū o -2, kia riro ko 9.

$$-\frac{23}{3}-9$$

Tangohia te 9 i te -\frac{23}{3}, ka -\frac{50}{3}.

$$-\frac{50}{3}$$

Tauwehe

$$-\frac{50}{3} = -16\frac{2}{3} = -16.666666666666668$$
