Whakaoti i te {left(61/2right)}^3-21^2/4-1

$${ \left(6 \frac{ 1 }{ 2 } \right) }^{ 3 } -2 \frac{ { 1 }^{ 2 } }{ 4 } -1$$

Aromātai

$$\frac{2185}{8}=273.125$$

Ngā Upane Otinga

Whakareatia te 6 ki te 2, ka 12.

$$\left(\frac{12+1}{2}\right)^{3}-2\times \frac{1^{2}}{4}-1$$

Tāpirihia te 12 ki te 1, ka 13.

$$\left(\frac{13}{2}\right)^{3}-2\times \frac{1^{2}}{4}-1$$

Tātaihia te \frac{13}{2} mā te pū o 3, kia riro ko \frac{2197}{8}.

$$\frac{2197}{8}-2\times \frac{1^{2}}{4}-1$$

Tātaihia te 1 mā te pū o 2, kia riro ko 1.

$$\frac{2197}{8}-2\times \frac{1}{4}-1$$

Whakareatia te 2 ki te \frac{1}{4}, ka \frac{1}{2}.

$$\frac{2197}{8}-\frac{1}{2}-1$$

Tangohia te \frac{1}{2} i te \frac{2197}{8}, ka \frac{2193}{8}.

$$\frac{2193}{8}-1$$

Tangohia te 1 i te \frac{2193}{8}, ka \frac{2185}{8}.

$$\frac{2185}{8}$$

Tauwehe

$$\frac{5 \cdot 19 \cdot 23}{2 ^ {3}} = 273\frac{1}{8} = 273.125$$
