Whakaoti i te -15*3/2b

$$- 15 \cdot \frac { 3 } { 2 } b$$

Aromātai

$$-\frac{45b}{2}$$

Ngā Upane Otinga

Tuhia te -15\times \frac{3}{2} hei hautanga kotahi.

$$\frac{-15\times 3}{2}b$$

Whakareatia te -15 ki te 3, ka -45.

$$\frac{-45}{2}b$$

Ka taea te hautanga \frac{-45}{2} te tuhi anō ko -\frac{45}{2} mā te tango i te tohu tōraro.

$$-\frac{45}{2}b$$

Kimi Pārōnaki e ai ki b

$$-\frac{45}{2} = -22\frac{1}{2} = -22.5$$

Ngā Upane e Whakamahi ana i te Tautuhinga o te Pārōnaki

Tuhia te -15\times \frac{3}{2} hei hautanga kotahi.

$$\frac{\mathrm{d}}{\mathrm{d}b}(\frac{-15\times 3}{2}b)$$

Whakareatia te -15 ki te 3, ka -45.

$$\frac{\mathrm{d}}{\mathrm{d}b}(\frac{-45}{2}b)$$

Ka taea te hautanga \frac{-45}{2} te tuhi anō ko -\frac{45}{2} mā te tango i te tohu tōraro.

$$\frac{\mathrm{d}}{\mathrm{d}b}(-\frac{45}{2}b)$$

Ko te pārōnaki o ax^{n} ko nax^{n-1}.

$$-\frac{45}{2}b^{1-1}$$

Tango 1 mai i 1.

$$-\frac{45}{2}b^{0}$$

Mō tētahi kupu t mahue te 0, t^{0}=1.

$$-\frac{45}{2}$$
