Whakaoti i te 4000=c^2

$$4000 = c ^ { 2 }$$

Whakaoti mō c

$$c=20\sqrt{10}\approx 63.245553203$$

$$c=-20\sqrt{10}\approx -63.245553203$$

Ngā Upane mā te Kimi Pūtakerua

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

$$c^{2}=4000$$

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

$$c=20\sqrt{10} c=-20\sqrt{10}$$

Ngā Upane e Whakamahi ana i te Tikanga Tātai Pūrua

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

$$c^{2}=4000$$

Tangohia te 4000 mai i ngā taha e rua.

$$c^{2}-4000=0$$

Kei te āhua arowhānui tēnei whārite: ax^{2}+bx+c=0. Me whakakapi 1 mō a, 0 mō b, me -4000 mō c i te tikanga tātai pūrua, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.

$$c=\frac{0±\sqrt{0^{2}-4\left(-4000\right)}}{2}$$

Pūrua 0.

$$c=\frac{0±\sqrt{-4\left(-4000\right)}}{2}$$

Whakareatia -4 ki te -4000.

$$c=\frac{0±\sqrt{16000}}{2}$$

Tuhia te pūtakerua o te 16000.

$$c=\frac{0±40\sqrt{10}}{2}$$

Nā, me whakaoti te whārite c=\frac{0±40\sqrt{10}}{2} ina he tāpiri te ±.

$$c=20\sqrt{10}$$

Nā, me whakaoti te whārite c=\frac{0±40\sqrt{10}}{2} ina he tango te ±.

$$c=-20\sqrt{10}$$

Kua oti te whārite te whakatau.

$$c=20\sqrt{10} c=-20\sqrt{10}$$
