Whakaoti i te sqrt[4]{1/81}+(2/3)^-1-0.002*10^3

$$\sqrt[ 4 ] { \frac { 1 } { 81 } } + ( \frac { 2 } { 3 } ) ^ { - 1 } - 0.002 \times 10 ^ { 3 }$$

Aromātai

$$-\frac{1}{6}\approx -0.166666667$$

Ngā Upane Otinga

Tātaitia te \sqrt[4]{\frac{1}{81}} kia tae ki \frac{1}{3}.

$$\frac{1}{3}+\left(\frac{2}{3}\right)^{-1}-0.002\times 10^{3}$$

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

$$\frac{1}{3}+\frac{3}{2}-0.002\times 10^{3}$$

Tāpirihia te \frac{1}{3} ki te \frac{3}{2}, ka \frac{11}{6}.

$$\frac{11}{6}-0.002\times 10^{3}$$

Tātaihia te 10 mā te pū o 3, kia riro ko 1000.

$$\frac{11}{6}-0.002\times 1000$$

Whakareatia te 0.002 ki te 1000, ka 2.

$$\frac{11}{6}-2$$

Tangohia te 2 i te \frac{11}{6}, ka -\frac{1}{6}.

$$-\frac{1}{6}$$

Tauwehe

$$-\frac{1}{6} = -0.16666666666666666$$
