Whakaoti i te 2-(-7/4)^2+(-5/8)

$$2 - ( - \frac { 7 } { 4 } ) ^ { 2 } + ( - \frac { 5 } { 8 } )$$

Aromātai

$$-\frac{27}{16}=-1.6875$$

Ngā Upane Otinga

Tātaihia te -\frac{7}{4} mā te pū o 2, kia riro ko \frac{49}{16}.

$$2-\frac{49}{16}-\frac{5}{8}$$

Me tahuri te 2 ki te hautau \frac{32}{16}.

$$\frac{32}{16}-\frac{49}{16}-\frac{5}{8}$$

Tā te mea he rite te tauraro o \frac{32}{16} me \frac{49}{16}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{32-49}{16}-\frac{5}{8}$$

Tangohia te 49 i te 32, ka -17.

$$-\frac{17}{16}-\frac{5}{8}$$

Ko te maha noa iti rawa atu o 16 me 8 ko 16. Me tahuri -\frac{17}{16} me \frac{5}{8} ki te hautau me te tautūnga 16.

$$-\frac{17}{16}-\frac{10}{16}$$

Tā te mea he rite te tauraro o -\frac{17}{16} me \frac{10}{16}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{-17-10}{16}$$

Tangohia te 10 i te -17, ka -27.

$$-\frac{27}{16}$$

Tauwehe

$$-\frac{27}{16} = -1\frac{11}{16} = -1.6875$$
