Kua tāruatia ki te papatopenga
3\left(x^{7}y-27x^{4}y^{4}\right)
Tauwehea te 3.
x^{4}y\left(x^{3}-27y^{3}\right)
Whakaarohia te x^{7}y-27x^{4}y^{4}. Tauwehea te x^{4}y.
\left(x-3y\right)\left(x^{2}+3xy+9y^{2}\right)
Whakaarohia te x^{3}-27y^{3}. Tuhia anō te x^{3}-27y^{3} hei x^{3}-\left(3y\right)^{3}. Ka taea te rerekētanga o ngā pūtoru te whakatauwehe mā te whakamahi i te ture: a^{3}-b^{3}=\left(a-b\right)\left(a^{2}+ab+b^{2}\right).
3x^{4}y\left(x-3y\right)\left(x^{2}+3xy+9y^{2}\right)
Me tuhi anō te kīanga whakatauwehe katoa.
