Kua tāruatia ki te papatopenga
\left(3u+4\right)\left(9u^{2}-12u+16\right)
Tuhia anō te 64+27u^{3} hei \left(3u\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 9u^{2}-12u+16 i whakatauwehea i te mea kāhore ōna pūtake whakahau.
