Whakareatia te 10 ki te 1.5, ka 15.

$$\frac{\mathrm{d}}{\mathrm{d}r}(15r\times 5\times 4)$$

Whakareatia te 15 ki te 5, ka 75.

$$\frac{\mathrm{d}}{\mathrm{d}r}(75r\times 4)$$

Whakareatia te 75 ki te 4, ka 300.

$$\frac{\mathrm{d}}{\mathrm{d}r}(300r)$$

Ko te pārōnaki o ax^{n} ko nax^{n-1}.

$$300r^{1-1}$$

Tango 1 mai i 1.
