Whakaoti i te 2*4/4^2+3-(-2)*4/(-2)^2+3

$$\frac { 2 \times 4 } { 4 ^ { 2 } + 3 } - \frac { ( - 2 ) \times 4 } { ( - 2 ) ^ { 2 } + 3 }$$

Aromātai

$$\frac{208}{133}\approx 1.563909774$$

Ngā Upane Otinga

Whakareatia te 2 ki te 4, ka 8.

$$\frac{8}{4^{2}+3}-\frac{-2\times 4}{\left(-2\right)^{2}+3}$$

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

$$\frac{8}{16+3}-\frac{-2\times 4}{\left(-2\right)^{2}+3}$$

Tāpirihia te 16 ki te 3, ka 19.

$$\frac{8}{19}-\frac{-2\times 4}{\left(-2\right)^{2}+3}$$

Whakareatia te -2 ki te 4, ka -8.

$$\frac{8}{19}-\frac{-8}{\left(-2\right)^{2}+3}$$

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

$$\frac{8}{19}-\frac{-8}{4+3}$$

Tāpirihia te 4 ki te 3, ka 7.

$$\frac{8}{19}-\frac{-8}{7}$$

Ka taea te hautanga \frac{-8}{7} te tuhi anō ko -\frac{8}{7} mā te tango i te tohu tōraro.

$$\frac{8}{19}-\left(-\frac{8}{7}\right)$$

Ko te tauaro o -\frac{8}{7} ko \frac{8}{7}.

$$\frac{8}{19}+\frac{8}{7}$$

Ko te maha noa iti rawa atu o 19 me 7 ko 133. Me tahuri \frac{8}{19} me \frac{8}{7} ki te hautau me te tautūnga 133.

$$\frac{56}{133}+\frac{152}{133}$$

Tā te mea he rite te tauraro o \frac{56}{133} me \frac{152}{133}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{56+152}{133}$$

Tāpirihia te 56 ki te 152, ka 208.

$$\frac{208}{133}$$

Tauwehe

$$\frac{2 ^ {4} \cdot 13}{7 \cdot 19} = 1\frac{75}{133} = 1.5639097744360901$$
