Whakaoti i te 4^2*5^2div2=sqrt{x}

$$4 ^ { 2 } \times 5 ^ { 2 } \div 2 = \sqrt { x }$$

Whakaoti mō x

$$x=40000$$

Ngā Upane mō te Whakaoti Whārite Pūtake

Whakareatia ngā taha e rua o te whārite ki te 2.

$$4^{2}\times 5^{2}=2\sqrt{x}$$

Tātaihia te 4 mā te pū o 2, kia riro ko 16.

$$16\times 5^{2}=2\sqrt{x}$$

Tātaihia te 5 mā te pū o 2, kia riro ko 25.

$$16\times 25=2\sqrt{x}$$

Whakareatia te 16 ki te 25, ka 400.

$$400=2\sqrt{x}$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$2\sqrt{x}=400$$

Whakawehea ngā taha e rua ki te 2.

$$\sqrt{x}=\frac{400}{2}$$

Whakawehea te 400 ki te 2, kia riro ko 200.

$$\sqrt{x}=200$$

Pūruatia ngā taha e rua o te whārite.

$$x=40000$$
