Whakaoti i te y=40^2-11/10(1.3)

$$y = 40 ^ { 2 } - 1 \frac { 1 } { 10 } ( 1.3 )$$

Whakaoti mō y

$$y=1598.57$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tātaihia te 40 mā te pū o 2, kia riro ko 1600.

$$y=1600-\frac{1\times 10+1}{10}\times 1.3$$

Whakareatia te 1 ki te 10, ka 10.

$$y=1600-\frac{10+1}{10}\times 1.3$$

Tāpirihia te 10 ki te 1, ka 11.

$$y=1600-\frac{11}{10}\times 1.3$$

Me tahuri ki tau ā-ira 1.3 ki te hautau \frac{13}{10}.

$$y=1600-\frac{11}{10}\times \frac{13}{10}$$

Me whakarea te \frac{11}{10} ki te \frac{13}{10} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$y=1600-\frac{11\times 13}{10\times 10}$$

Mahia ngā whakarea i roto i te hautanga \frac{11\times 13}{10\times 10}.

$$y=1600-\frac{143}{100}$$

Me tahuri te 1600 ki te hautau \frac{160000}{100}.

$$y=\frac{160000}{100}-\frac{143}{100}$$

Tā te mea he rite te tauraro o \frac{160000}{100} me \frac{143}{100}, me tango rāua mā te tango i ō raua taurunga.

$$y=\frac{160000-143}{100}$$

Tangohia te 143 i te 160000, ka 159857.

$$y=\frac{159857}{100}$$

Tautapa y

$$y≔1598.57$$
