\left(3y+4\right)\left(9y^{2}-12y+16\right)
Tuhia anō te 64+27y^{3} hei \left(3y\right)^{3}+4^{3}. Ka taea te tapeke pūtoru te whakatauwehe mā te whakamahi i te ture: a^{3}+b^{3}=\left(a+b\right)\left(a^{2}-ab+b^{2}\right). Kāore te pūrau 9y^{2}-12y+16 i whakatauwehea i te mea kāhore ōna pūtake whakahau.
