\left(a^{2}-9\right)\left(a^{2}+9\right)
Tuhia anō te a^{4}-81 hei \left(a^{2}\right)^{2}-9^{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).
\left(a-3\right)\left(a+3\right)
Whakaarohia te a^{2}-9. Tuhia anō te a^{2}-9 hei a^{2}-3^{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).
\left(a-3\right)\left(a+3\right)\left(a^{2}+9\right)
Me tuhi anō te kīanga whakatauwehe katoa. Kāore te pūrau a^{2}+9 i whakatauwehea i te mea kāhore ōna pūtake whakahau.
