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}.

$$\left(2\sqrt{3}\right)^{2}-1^{2}$$

Whakarohaina te \left(2\sqrt{3}\right)^{2}.

$$2^{2}\left(\sqrt{3}\right)^{2}-1^{2}$$

Tātaihia te 2 mā te pū o 2, kia riro ko 4.

$$4\left(\sqrt{3}\right)^{2}-1^{2}$$

Ko te pūrua o \sqrt{3} ko 3.

$$4\times 3-1^{2}$$

Whakareatia te 4 ki te 3, ka 12.

$$12-1^{2}$$

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

$$12-1$$

Tangohia te 1 i te 12, ka 11.

$$11$$
