Ngā Upane Otinga

Hei whakarea i ngā pū o te pūtake kotahi, me tāpiri ō rātou taupū. Tāpiria te 0 me te 1 kia riro ai te 1.

$$\frac{\left(-7\right)^{5}\times 49^{2}}{7^{1}\left(-49\right)^{3}}$$

Tātaihia te -7 mā te pū o 5, kia riro ko -16807.

$$\frac{-16807\times 49^{2}}{7^{1}\left(-49\right)^{3}}$$

Tātaihia te 49 mā te pū o 2, kia riro ko 2401.

$$\frac{-16807\times 2401}{7^{1}\left(-49\right)^{3}}$$

Whakareatia te -16807 ki te 2401, ka -40353607.

$$\frac{-40353607}{7^{1}\left(-49\right)^{3}}$$

Tātaihia te 7 mā te pū o 1, kia riro ko 7.

$$\frac{-40353607}{7\left(-49\right)^{3}}$$

Tātaihia te -49 mā te pū o 3, kia riro ko -117649.

$$\frac{-40353607}{7\left(-117649\right)}$$

Whakareatia te 7 ki te -117649, ka -823543.

$$\frac{-40353607}{-823543}$$

Whakawehea te -40353607 ki te -823543, kia riro ko 49.
