Whakaoti i te (4+1/3)(n-1/3)

$$( 4 + \frac { 1 } { 3 } ) ( n - \frac { 1 } { 3 } )$$

Aromātai

$$\frac{13n}{3}-\frac{13}{9}$$

Ngā Upane Otinga

Me tahuri te 4 ki te hautau \frac{12}{3}.

$$\left(\frac{12}{3}+\frac{1}{3}\right)\left(n-\frac{1}{3}\right)$$

Tā te mea he rite te tauraro o \frac{12}{3} me \frac{1}{3}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{12+1}{3}\left(n-\frac{1}{3}\right)$$

Tāpirihia te 12 ki te 1, ka 13.

$$\frac{13}{3}\left(n-\frac{1}{3}\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te \frac{13}{3} ki te n-\frac{1}{3}.

$$\frac{13}{3}n+\frac{13}{3}\left(-\frac{1}{3}\right)$$

Me whakarea te \frac{13}{3} ki te -\frac{1}{3} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{13}{3}n+\frac{13\left(-1\right)}{3\times 3}$$

Mahia ngā whakarea i roto i te hautanga \frac{13\left(-1\right)}{3\times 3}.

$$\frac{13}{3}n+\frac{-13}{9}$$

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

$$\frac{13}{3}n-\frac{13}{9}$$

Whakaroha
