Whakaoti i te 2/5x*15/2

$$\frac { 2 } { 5 } x \times \frac { 15 } { 2 }$$

Aromātai

$$3x$$

Ngā Upane Otinga

Me whakarea te \frac{2}{5} ki te \frac{15}{2} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{2\times 15}{5\times 2}x$$

Me whakakore tahi te 2 i te taurunga me te tauraro.

$$\frac{15}{5}x$$

Whakawehea te 15 ki te 5, kia riro ko 3.

$$3x$$

Kimi Pārōnaki e ai ki x

$$3$$

Ngā Upane e Whakamahi ana i te Tautuhinga o te Pārōnaki

Me whakarea te \frac{2}{5} ki te \frac{15}{2} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{\mathrm{d}}{\mathrm{d}x}(\frac{2\times 15}{5\times 2}x)$$

Me whakakore tahi te 2 i te taurunga me te tauraro.

$$\frac{\mathrm{d}}{\mathrm{d}x}(\frac{15}{5}x)$$

Whakawehea te 15 ki te 5, kia riro ko 3.

$$\frac{\mathrm{d}}{\mathrm{d}x}(3x)$$

Ko te pārōnaki o ax^{n} ko nax^{n-1}.

$$3x^{1-1}$$

Tango 1 mai i 1.

$$3x^{0}$$

Mō tētahi kupu t mahue te 0, t^{0}=1.

$$3\times 1$$

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

$$3$$
