Whakaoti i te -4*3+8-(-20)/sqrt{(-4)^2+1}

$$\frac { - 4 \cdot 3 + 8 - ( - 20 ) } { \sqrt { ( - 4 ) ^ { 2 } + 1 } }$$

Aromātai

$$\frac{16\sqrt{17}}{17}\approx 3.880570001$$

Ngā Upane Otinga

Whakareatia te -4 ki te 3, ka -12.

$$\frac{-12+8-\left(-20\right)}{\sqrt{\left(-4\right)^{2}+1}}$$

Tāpirihia te -12 ki te 8, ka -4.

$$\frac{-4-\left(-20\right)}{\sqrt{\left(-4\right)^{2}+1}}$$

Ko te tauaro o -20 ko 20.

$$\frac{-4+20}{\sqrt{\left(-4\right)^{2}+1}}$$

Tāpirihia te -4 ki te 20, ka 16.

$$\frac{16}{\sqrt{\left(-4\right)^{2}+1}}$$

Tātaihia te -4 mā te pū o 2, kia riro ko 16.

$$\frac{16}{\sqrt{16+1}}$$

Tāpirihia te 16 ki te 1, ka 17.

$$\frac{16}{\sqrt{17}}$$

Whakangāwaritia te tauraro o \frac{16}{\sqrt{17}} mā te whakarea i te taurunga me te tauraro ki te \sqrt{17}.

$$\frac{16\sqrt{17}}{\left(\sqrt{17}\right)^{2}}$$

Ko te pūrua o \sqrt{17} ko 17.

$$\frac{16\sqrt{17}}{17}$$
