Whakaoti i te 1+1=xx.360=

$$1+1=xx.360=$$

Whakaoti mō x

$$x = \frac{5 \sqrt{2}}{3} \approx 2.357022604$$

$$x = -\frac{5 \sqrt{2}}{3} \approx -2.357022604$$

Ngā Upane mā te Kimi Pūtakerua

Whakareatia te x ki te x, ka x^{2}.

$$1+1=x^{2}\times 0.36$$

Tāpirihia te 1 ki te 1, ka 2.

$$2=x^{2}\times 0.36$$

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

$$x^{2}\times 0.36=2$$

Whakawehea ngā taha e rua ki te 0.36.

$$x^{2}=\frac{2}{0.36}$$

Whakarohaina te \frac{2}{0.36} mā te whakarea i te taurunga me te tauraro ki te 100.

$$x^{2}=\frac{200}{36}$$

Whakahekea te hautanga \frac{200}{36} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$x^{2}=\frac{50}{9}$$

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

$$x=\frac{5\sqrt{2}}{3} x=-\frac{5\sqrt{2}}{3}$$

Ngā Upane e Whakamahi ana i te Tikanga Tātai Pūrua

Whakareatia te x ki te x, ka x^{2}.

$$1+1=x^{2}\times 0.36$$

Tāpirihia te 1 ki te 1, ka 2.

$$2=x^{2}\times 0.36$$

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

$$x^{2}\times 0.36=2$$

Tangohia te 2 mai i ngā taha e rua.

$$x^{2}\times 0.36-2=0$$

Ko ngā tikanga tātai pūrua pēnei i tēnei nā, me te kīanga tau x^{2} engari kāore he kīanga tau x, ka taea tonu te whakaoti mā te whakamahi i te tikanga tātai pūrua, \frac{-b±\sqrt{b^{2}-4ac}}{2a}, ina tuhia ki te tānga ngahuru: ax^{2}+bx+c=0.

$$0.36x^{2}-2=0$$

Kei te āhua arowhānui tēnei whārite: ax^{2}+bx+c=0. Me whakakapi 0.36 mō a, 0 mō b, me -2 mō c i te tikanga tātai pūrua, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.

$$x=\frac{0±\sqrt{0^{2}-4\times 0.36\left(-2\right)}}{2\times 0.36}$$

Pūrua 0.

$$x=\frac{0±\sqrt{-4\times 0.36\left(-2\right)}}{2\times 0.36}$$

Whakareatia -4 ki te 0.36.

$$x=\frac{0±\sqrt{-1.44\left(-2\right)}}{2\times 0.36}$$

Whakareatia -1.44 ki te -2.

$$x=\frac{0±\sqrt{2.88}}{2\times 0.36}$$

Tuhia te pūtakerua o te 2.88.

$$x=\frac{0±\frac{6\sqrt{2}}{5}}{2\times 0.36}$$

Whakareatia 2 ki te 0.36.

$$x=\frac{0±\frac{6\sqrt{2}}{5}}{0.72}$$

Nā, me whakaoti te whārite x=\frac{0±\frac{6\sqrt{2}}{5}}{0.72} ina he tāpiri te ±.

$$x=\frac{5\sqrt{2}}{3}$$

Nā, me whakaoti te whārite x=\frac{0±\frac{6\sqrt{2}}{5}}{0.72} ina he tango te ±.

$$x=-\frac{5\sqrt{2}}{3}$$

Kua oti te whārite te whakatau.

$$x=\frac{5\sqrt{2}}{3} x=-\frac{5\sqrt{2}}{3}$$
