Whakaoti i te -3^2quadtext{II}47^2-3^4:9

$$- 3 ^ { 2 } \quad \text { II } 47 ^ { 2 } - 3 ^ { 4 } : 9$$

Aromātai

$$-19881I^{2}-9$$

Ngā Upane Otinga

Whakareatia te I ki te I, ka I^{2}.

$$\left(-3^{2}\right)I^{2}\times 47^{2}-\frac{3^{4}}{9}$$

Tātaihia te 3 mā te pū o 2, kia riro ko 9.

$$-9I^{2}\times 47^{2}-\frac{3^{4}}{9}$$

Tātaihia te 47 mā te pū o 2, kia riro ko 2209.

$$-9I^{2}\times 2209-\frac{3^{4}}{9}$$

Whakareatia te -9 ki te 2209, ka -19881.

$$-19881I^{2}-\frac{3^{4}}{9}$$

Tātaihia te 3 mā te pū o 4, kia riro ko 81.

$$-19881I^{2}-\frac{81}{9}$$

Whakawehea te 81 ki te 9, kia riro ko 9.

$$-19881I^{2}-9$$

Tauwehe

$$9\left(-2209I^{2}-1\right)$$

Ngā Upane Otinga

Tauwehea te 9. Kāore te pūrau -2209I^{2}-1 i whakatauwehea i te mea kāhore ōna pūtake whakahau.

$$9\left(-2209II-1\right)$$
