Whakaoti i te V^2=1024

$$V ^ { 2 } = 1024$$

Whakaoti mō V

$$V=32$$

$$V=-32$$

Ngā Hipanga Whakamahi Rerekētanga o ngā Pūrua

Tangohia te 1024 mai i ngā taha e rua.

$$V^{2}-1024=0$$

Whakaarohia te V^{2}-1024. Tuhia anō te V^{2}-1024 hei V^{2}-32^{2}. Ka taea te rerekētanga o ngā pūrua te whakatauwehe mā te ture: a^{2}-b^{2}=\left(a-b\right)\left(a+b\right).

$$\left(V-32\right)\left(V+32\right)=0$$

Hei kimi otinga whārite, me whakaoti te V-32=0 me te V+32=0.

$$V=32 V=-32$$

Ngā Upane mā te Kimi Pūtakerua

Tuhia te pūtakerua o ngā taha e rua o te whārite.

$$V=32 V=-32$$

Ngā Upane e Whakamahi ana i te Tikanga Tātai Pūrua

Tangohia te 1024 mai i ngā taha e rua.

$$V^{2}-1024=0$$

Kei te āhua arowhānui tēnei whārite: ax^{2}+bx+c=0. Me whakakapi 1 mō a, 0 mō b, me -1024 mō c i te tikanga tātai pūrua, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.

$$V=\frac{0±\sqrt{0^{2}-4\left(-1024\right)}}{2}$$

Pūrua 0.

$$V=\frac{0±\sqrt{-4\left(-1024\right)}}{2}$$

Whakareatia -4 ki te -1024.

$$V=\frac{0±\sqrt{4096}}{2}$$

Tuhia te pūtakerua o te 4096.

$$V=\frac{0±64}{2}$$

Nā, me whakaoti te whārite V=\frac{0±64}{2} ina he tāpiri te ±. Whakawehe 64 ki te 2.

$$V=32$$

Nā, me whakaoti te whārite V=\frac{0±64}{2} ina he tango te ±. Whakawehe -64 ki te 2.

$$V=-32$$

Kua oti te whārite te whakatau.

$$V=32 V=-32$$
