Whakaoti i te (3y-5)+(2y-8)=?

$$( 3 y - 5 ) + ( 2 y - 8 ) = ?$$

Aromātai

$$5y-13$$

Ngā Upane Otinga

Pahekotia te 3y me 2y, ka 5y.

$$5y-5-8$$

Tangohia te 8 i te -5, ka -13.

$$5y-13$$

Kimi Pārōnaki e ai ki y

$$5$$

Ngā Upane e Whakamahi ana i te Ture Pārōnaki mō te Tapeke

Pahekotia te 3y me 2y, ka 5y.

$$\frac{\mathrm{d}}{\mathrm{d}y}(5y-5-8)$$

Tangohia te 8 i te -5, ka -13.

$$\frac{\mathrm{d}}{\mathrm{d}y}(5y-13)$$

Ko te pārōnaki o tētahi pūrau ko te tapeke o ngā pārōnaki o ōna kīanga tau. Ko te pārōnaki o tētahi kīanga tau pūmau ko 0. Ko te pārōnaki o te ax^{n} ko te nax^{n-1}.

$$5y^{1-1}$$

Tango 1 mai i 1.

$$5y^{0}$$

Mō tētahi kupu t mahue te 0, t^{0}=1.

$$5\times 1$$

Mō tētahi kupu t, t\times 1=t me 1t=t.
