Whakaoti i te sqrt{1-(n-2)}=2

$$\sqrt { 1 - ( n - 2 ) } = 2$$

Whakaoti mō n

$$n=-1$$

Ngā Upane mō te Whakaoti Whārite Pūtake

Hei kimi i te tauaro o n-2, kimihia te tauaro o ia taurangi.

$$\sqrt{1-n-\left(-2\right)}=2$$

Ko te tauaro o -2 ko 2.

$$\sqrt{1-n+2}=2$$

Tāpirihia te 1 ki te 2, ka 3.

$$\sqrt{3-n}=2$$

Pūruatia ngā taha e rua o te whārite.

$$-n+3=4$$

Me tango 3 mai i ngā taha e rua o te whārite.

$$-n+3-3=4-3$$

Mā te tango i te 3 i a ia ake anō ka toe ko te 0.

$$-n=4-3$$

Tango 3 mai i 4.

$$-n=1$$

Whakawehea ngā taha e rua ki te -1.

$$\frac{-n}{-1}=\frac{1}{-1}$$

Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.

$$n=\frac{1}{-1}$$

Whakawehe 1 ki te -1.

$$n=-1$$
