Whakaoti i te {left(3/2right)}^2+3*3/2-2

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

Aromātai

$$\frac{19}{4}=4.75$$

Ngā Upane Otinga

Tātaihia te \frac{3}{2} mā te pū o 2, kia riro ko \frac{9}{4}.

$$\frac{9}{4}+3\times \frac{3}{2}-2$$

Tuhia te 3\times \frac{3}{2} hei hautanga kotahi.

$$\frac{9}{4}+\frac{3\times 3}{2}-2$$

Whakareatia te 3 ki te 3, ka 9.

$$\frac{9}{4}+\frac{9}{2}-2$$

Ko te maha noa iti rawa atu o 4 me 2 ko 4. Me tahuri \frac{9}{4} me \frac{9}{2} ki te hautau me te tautūnga 4.

$$\frac{9}{4}+\frac{18}{4}-2$$

Tā te mea he rite te tauraro o \frac{9}{4} me \frac{18}{4}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{9+18}{4}-2$$

Tāpirihia te 9 ki te 18, ka 27.

$$\frac{27}{4}-2$$

Me tahuri te 2 ki te hautau \frac{8}{4}.

$$\frac{27}{4}-\frac{8}{4}$$

Tā te mea he rite te tauraro o \frac{27}{4} me \frac{8}{4}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{27-8}{4}$$

Tangohia te 8 i te 27, ka 19.

$$\frac{19}{4}$$

Tauwehe

$$\frac{19}{2 ^ {2}} = 4\frac{3}{4} = 4.75$$
