Whakaoti i te 2x/frac{5{20}}

$$\frac { 2 x } { \frac { 5 } { 20 } }$$

Aromātai

$$8x$$

Ngā Upane Otinga

Whakawehe 2x ki te \frac{5}{20} mā te whakarea 2x ki te tau huripoki o \frac{5}{20}.

$$\frac{2x\times 20}{5}$$

Whakareatia te 2 ki te 20, ka 40.

$$\frac{40x}{5}$$

Whakawehea te 40x ki te 5, kia riro ko 8x.

$$8x$$

Kimi Pārōnaki e ai ki x

$$8$$

Ngā Upane e Whakamahi ana i te Tautuhinga o te Pārōnaki

Whakawehe 2x ki te \frac{5}{20} mā te whakarea 2x ki te tau huripoki o \frac{5}{20}.

$$\frac{\mathrm{d}}{\mathrm{d}x}(\frac{2x\times 20}{5})$$

Whakareatia te 2 ki te 20, ka 40.

$$\frac{\mathrm{d}}{\mathrm{d}x}(\frac{40x}{5})$$

Whakawehea te 40x ki te 5, kia riro ko 8x.

$$\frac{\mathrm{d}}{\mathrm{d}x}(8x)$$

Ko te pārōnaki o ax^{n} ko nax^{n-1}.

$$8x^{1-1}$$

Tango 1 mai i 1.

$$8x^{0}$$

Mō tētahi kupu t mahue te 0, t^{0}=1.

$$8\times 1$$

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

$$8$$
