$$1800 x .2 \times 20$$

Aromātai

$$7200x$$

Ngā Upane Otinga

Whakareatia te 1800 ki te 0.2, ka 360.

$$360x\times 20$$

Whakareatia te 360 ki te 20, ka 7200.

$$7200x$$

Kimi Pārōnaki e ai ki x

$$7200$$

Ngā Upane e Whakamahi ana i te Tautuhinga o te Pārōnaki

Whakareatia te 1800 ki te 0.2, ka 360.

$$\frac{\mathrm{d}}{\mathrm{d}x}(360x\times 20)$$

Whakareatia te 360 ki te 20, ka 7200.

$$\frac{\mathrm{d}}{\mathrm{d}x}(7200x)$$

Ko te pārōnaki o ax^{n} ko nax^{n-1}.

$$7200x^{1-1}$$

Tango 1 mai i 1.

$$7200x^{0}$$

Mō tētahi kupu t mahue te 0, t^{0}=1.

$$7200\times 1$$

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

$$7200$$
