Whakaoti i te x=2184000*1.2^3(1.2-1)/1.2^3-1

$$x = \frac { 2184000 \cdot 1.2 ^ { 3 } ( 1.2 - 1 ) } { 1.2 ^ { 3 } - 1 }$$

Whakaoti mō x

$$x=1036800$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

$$x=\frac{2184000\times 1.728\left(1.2-1\right)}{1.2^{3}-1}$$

Whakareatia te 2184000 ki te 1.728, ka 3773952.

$$x=\frac{3773952\left(1.2-1\right)}{1.2^{3}-1}$$

Tangohia te 1 i te 1.2, ka 0.2.

$$x=\frac{3773952\times 0.2}{1.2^{3}-1}$$

Whakareatia te 3773952 ki te 0.2, ka 754790.4.

$$x=\frac{754790.4}{1.2^{3}-1}$$

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

$$x=\frac{754790.4}{1.728-1}$$

Tangohia te 1 i te 1.728, ka 0.728.

$$x=\frac{754790.4}{0.728}$$

Whakarohaina te \frac{754790.4}{0.728} mā te whakarea i te taurunga me te tauraro ki te 1000.

$$x=\frac{754790400}{728}$$

Whakawehea te 754790400 ki te 728, kia riro ko 1036800.

$$x=1036800$$

Tautapa x

$$x≔1036800$$
