Whakaoti i te x^3(-5/4x^2y)(2/5x^3y^4)

$$x ^ { 3 } ( - \frac { 5 } { 4 } x ^ { 2 } y ) ( \frac { 2 } { 5 } x ^ { 3 } y ^ { 4 } )$$

Aromātai

$$-\frac{y^{5}x^{8}}{2}$$

Ngā Upane Otinga

Hei whakarea i ngā pū o te pūtake kotahi, me tāpiri ō rātou taupū. Tāpiria te 3 me te 2 kia riro ai te 5.

$$x^{5}\left(-\frac{5}{4}\right)y\times \frac{2}{5}x^{3}y^{4}$$

Hei whakarea i ngā pū o te pūtake kotahi, me tāpiri ō rātou taupū. Tāpiria te 5 me te 3 kia riro ai te 8.

$$x^{8}\left(-\frac{5}{4}\right)y\times \frac{2}{5}y^{4}$$

Hei whakarea i ngā pū o te pūtake kotahi, me tāpiri ō rātou taupū. Tāpiria te 1 me te 4 kia riro ai te 5.

$$x^{8}\left(-\frac{5}{4}\right)y^{5}\times \frac{2}{5}$$

Whakareatia te -\frac{5}{4} ki te \frac{2}{5}, ka -\frac{1}{2}.

$$x^{8}\left(-\frac{1}{2}\right)y^{5}$$
