Whakaoti i te 1/2+3(1/3-1)^3+4^-2

$$\frac { 1 } { 2 } + 3 ( \frac { 1 } { 3 } - 1 ) ^ { 3 } + 4 ^ { - 2 }$$

Aromātai

$$-\frac{47}{144}\approx -0.326388889$$

Ngā Upane Otinga

Tangohia te 1 i te \frac{1}{3}, ka -\frac{2}{3}.

$$\frac{1}{2}+3\left(-\frac{2}{3}\right)^{3}+4^{-2}$$

Tātaihia te -\frac{2}{3} mā te pū o 3, kia riro ko -\frac{8}{27}.

$$\frac{1}{2}+3\left(-\frac{8}{27}\right)+4^{-2}$$

Whakareatia te 3 ki te -\frac{8}{27}, ka -\frac{8}{9}.

$$\frac{1}{2}-\frac{8}{9}+4^{-2}$$

Tangohia te \frac{8}{9} i te \frac{1}{2}, ka -\frac{7}{18}.

$$-\frac{7}{18}+4^{-2}$$

Tātaihia te 4 mā te pū o -2, kia riro ko \frac{1}{16}.

$$-\frac{7}{18}+\frac{1}{16}$$

Tāpirihia te -\frac{7}{18} ki te \frac{1}{16}, ka -\frac{47}{144}.

$$-\frac{47}{144}$$

Tauwehe

$$-\frac{47}{144} = -0.3263888888888889$$
