Whakaoti i te 12divfrac{sqrt{10}}{5}-1.6*50

$$12 \div \frac{ \sqrt{ 10 } }{ 5 } -1.6 \times 50$$

Aromātai

$$6\sqrt{10}-80\approx -61.026334039$$

Ngā Upane Otinga

Whakawehe 12 ki te \frac{\sqrt{10}}{5} mā te whakarea 12 ki te tau huripoki o \frac{\sqrt{10}}{5}.

$$\frac{12\times 5}{\sqrt{10}}-1.6\times 50$$

Whakareatia te 12 ki te 5, ka 60.

$$\frac{60}{\sqrt{10}}-1.6\times 50$$

Whakangāwaritia te tauraro o \frac{60}{\sqrt{10}} mā te whakarea i te taurunga me te tauraro ki te \sqrt{10}.

$$\frac{60\sqrt{10}}{\left(\sqrt{10}\right)^{2}}-1.6\times 50$$

Ko te pūrua o \sqrt{10} ko 10.

$$\frac{60\sqrt{10}}{10}-1.6\times 50$$

Whakawehea te 60\sqrt{10} ki te 10, kia riro ko 6\sqrt{10}.

$$6\sqrt{10}-1.6\times 50$$

Whakareatia te 1.6 ki te 50, ka 80.

$$6\sqrt{10}-80$$

Tauwehe

$$6 \sqrt{10} - 80 = -61.026334039$$
