Whakaoti i te (1-sqrt[3]{-8})-(10^-4+1/10)

$$( 1 - \sqrt[ 3 ] { - 8 } ) - ( 10 ^ { - 4 } + \frac { 1 } { 10 } )$$

Aromātai

$$\frac{28999}{10000}=2.8999$$

Ngā Upane Otinga

Tātaitia te \sqrt[3]{-8} kia tae ki -2.

$$1-\left(-2\right)-\left(10^{-4}+\frac{1}{10}\right)$$

Ko te tauaro o -2 ko 2.

$$1+2-\left(10^{-4}+\frac{1}{10}\right)$$

Tāpirihia te 1 ki te 2, ka 3.

$$3-\left(10^{-4}+\frac{1}{10}\right)$$

Tātaihia te 10 mā te pū o -4, kia riro ko \frac{1}{10000}.

$$3-\left(\frac{1}{10000}+\frac{1}{10}\right)$$

Tāpirihia te \frac{1}{10000} ki te \frac{1}{10}, ka \frac{1001}{10000}.

$$3-\frac{1001}{10000}$$

Tangohia te \frac{1001}{10000} i te 3, ka \frac{28999}{10000}.

$$\frac{28999}{10000}$$

Tauwehe

$$\frac{47 \cdot 617}{2 ^ {4} \cdot 5 ^ {4}} = 2\frac{8999}{10000} = 2.8999$$
