\frac{64a^{8}-1}{16}
Tauwehea te \frac{1}{16}.
\left(8a^{4}-1\right)\left(8a^{4}+1\right)
Whakaarohia te 64a^{8}-1. Tuhia anō te 64a^{8}-1 hei \left(8a^{4}\right)^{2}-1^{2}. Ka taea te rerekētanga o ngā pūrua te whakatauwehe mā te ture: p^{2}-q^{2}=\left(p-q\right)\left(p+q\right).
\frac{\left(8a^{4}-1\right)\left(8a^{4}+1\right)}{16}
Me tuhi anō te kīanga whakatauwehe katoa. Kāore i tauwehea ēnei pūrau i te mea kāhore ō rātou pūtake whakahau: 8a^{4}-1,8a^{4}+1.
