Whakaoti i te 4^2+6(4)-27/4^2-8(4)+7

$$\frac { 4 ^ { 2 } + 6 ( 4 ) - 27 } { 4 ^ { 2 } - 8 ( 4 ) + 7 }$$

Aromātai

$$-\frac{13}{9}\approx -1.444444444$$

Ngā Upane Otinga

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

$$\frac{16+6\times 4-27}{4^{2}-8\times 4+7}$$

Whakareatia te 6 ki te 4, ka 24.

$$\frac{16+24-27}{4^{2}-8\times 4+7}$$

Tāpirihia te 16 ki te 24, ka 40.

$$\frac{40-27}{4^{2}-8\times 4+7}$$

Tangohia te 27 i te 40, ka 13.

$$\frac{13}{4^{2}-8\times 4+7}$$

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

$$\frac{13}{16-8\times 4+7}$$

Whakareatia te 8 ki te 4, ka 32.

$$\frac{13}{16-32+7}$$

Tangohia te 32 i te 16, ka -16.

$$\frac{13}{-16+7}$$

Tāpirihia te -16 ki te 7, ka -9.

$$\frac{13}{-9}$$

Ka taea te hautanga \frac{13}{-9} te tuhi anō ko -\frac{13}{9} mā te tango i te tohu tōraro.

$$-\frac{13}{9}$$

Tauwehe

$$-\frac{13}{9} = -1\frac{4}{9} = -1.4444444444444444$$
