Ngā Upane Otinga

Ka taea te whakareanga te panoni ki te rerekētanga o ngā pūrua mā te ture: \left(a-b\right)\left(a+b\right)=a^{2}-b^{2}.

$$1^{2}-\left(8\sqrt{2}\right)^{2}$$

Tātaihia te 1 mā te pū o 2, kia riro ko 1.

$$1-\left(8\sqrt{2}\right)^{2}$$

Whakarohaina te \left(8\sqrt{2}\right)^{2}.

$$1-8^{2}\left(\sqrt{2}\right)^{2}$$

Tātaihia te 8 mā te pū o 2, kia riro ko 64.

$$1-64\left(\sqrt{2}\right)^{2}$$

Ko te pūrua o \sqrt{2} ko 2.

$$1-64\times 2$$

Whakareatia te 64 ki te 2, ka 128.

$$1-128$$

Tangohia te 128 i te 1, ka -127.
