Whakaoti i te 447=x^2

$$447 = x ^ { 2 }$$

Whakaoti mō x

$$x=\sqrt{447}\approx 21.142374512$$

$$x=-\sqrt{447}\approx -21.142374512$$

Ngā Upane mā te Kimi Pūtakerua

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

$$x^{2}=447$$

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

$$x=\sqrt{447} x=-\sqrt{447}$$

Ngā Upane e Whakamahi ana i te Tikanga Tātai Pūrua

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

$$x^{2}=447$$

Tangohia te 447 mai i ngā taha e rua.

$$x^{2}-447=0$$

Kei te āhua arowhānui tēnei whārite: ax^{2}+bx+c=0. Me whakakapi 1 mō a, 0 mō b, me -447 mō c i te tikanga tātai pūrua, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.

$$x=\frac{0±\sqrt{0^{2}-4\left(-447\right)}}{2}$$

Pūrua 0.

$$x=\frac{0±\sqrt{-4\left(-447\right)}}{2}$$

Whakareatia -4 ki te -447.

$$x=\frac{0±\sqrt{1788}}{2}$$

Tuhia te pūtakerua o te 1788.

$$x=\frac{0±2\sqrt{447}}{2}$$

Nā, me whakaoti te whārite x=\frac{0±2\sqrt{447}}{2} ina he tāpiri te ±.

$$x=\sqrt{447}$$

Nā, me whakaoti te whārite x=\frac{0±2\sqrt{447}}{2} ina he tango te ±.

$$x=-\sqrt{447}$$

Kua oti te whārite te whakatau.

$$x=\sqrt{447} x=-\sqrt{447}$$
