Whakaoti i te 11*1-3*3/(1+0.2)^3*30

$$\frac { 11 \cdot 1 - 3 \cdot 3 } { ( 1 + 0.2 ) ^ { 3 } } \times 30$$

Aromātai

$$\frac{625}{18}\approx 34.722222222$$

Ngā Upane Otinga

Whakareatia te 11 ki te 1, ka 11.

$$\frac{11-3\times 3}{\left(1+0.2\right)^{3}}\times 30$$

Whakareatia te 3 ki te 3, ka 9.

$$\frac{11-9}{\left(1+0.2\right)^{3}}\times 30$$

Tangohia te 9 i te 11, ka 2.

$$\frac{2}{\left(1+0.2\right)^{3}}\times 30$$

Tāpirihia te 1 ki te 0.2, ka 1.2.

$$\frac{2}{1.2^{3}}\times 30$$

Tātaihia te 1.2 mā te pū o 3, kia riro ko 1.728.

$$\frac{2}{1.728}\times 30$$

Whakarohaina te \frac{2}{1.728} mā te whakarea i te taurunga me te tauraro ki te 1000.

$$\frac{2000}{1728}\times 30$$

Whakahekea te hautanga \frac{2000}{1728} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 16.

$$\frac{125}{108}\times 30$$

Whakareatia te \frac{125}{108} ki te 30, ka \frac{625}{18}.

$$\frac{625}{18}$$

Tauwehe

$$\frac{5 ^ {4}}{2 \cdot 3 ^ {2}} = 34\frac{13}{18} = 34.72222222222222$$
