Whakaoti i te sqrt{2a}=a

$$\sqrt { 2 a } = a$$

Whakaoti mō a

$$a=2$$

$$a=0$$

Ngā Upane Otinga

Pūruatia ngā taha e rua o te whārite.

$$\left(\sqrt{2a}\right)^{2}=a^{2}$$

Tātaihia te \sqrt{2a} mā te pū o 2, kia riro ko 2a.

$$2a=a^{2}$$

Tangohia te a^{2} mai i ngā taha e rua.

$$2a-a^{2}=0$$

Tauwehea te a.

$$a\left(2-a\right)=0$$

Hei kimi otinga whārite, me whakaoti te a=0 me te 2-a=0.

$$a=0 a=2$$

Whakakapia te 0 mō te a i te whārite \sqrt{2a}=a.

$$\sqrt{2\times 0}=0$$

Whakarūnātia. Ko te uara a=0 kua ngata te whārite.

$$0=0$$

Whakakapia te 2 mō te a i te whārite \sqrt{2a}=a.

$$\sqrt{2\times 2}=2$$

Whakarūnātia. Ko te uara a=2 kua ngata te whārite.

$$2=2$$

Rārangihia ngā rongoā katoa o \sqrt{2a}=a.

$$a=0 a=2$$
