Whakaoti i te -3^-2+(-7/8)^0+(-1)^2020

$$- 3 ^ { - 2 } + ( - \frac { 7 } { 8 } ) ^ { 0 } + ( - 1 ) ^ { 2020 }$$

Aromātai

$$\frac{17}{9}\approx 1.888888889$$

Ngā Upane Otinga

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

$$-\frac{1}{9}+\left(-\frac{7}{8}\right)^{0}+\left(-1\right)^{2020}$$

Tātaihia te -\frac{7}{8} mā te pū o 0, kia riro ko 1.

$$-\frac{1}{9}+1+\left(-1\right)^{2020}$$

Tāpirihia te -\frac{1}{9} ki te 1, ka \frac{8}{9}.

$$\frac{8}{9}+\left(-1\right)^{2020}$$

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

$$\frac{8}{9}+1$$

Tāpirihia te \frac{8}{9} ki te 1, ka \frac{17}{9}.

$$\frac{17}{9}$$

Tauwehe

$$\frac{17}{3 ^ {2}} = 1\frac{8}{9} = 1.8888888888888888$$
