Whakaoti i te 16x^2/7:4x^3/21

$$\frac { 16 x ^ { 2 } } { 7 } : \frac { 4 x ^ { 3 } } { 21 }$$

Aromātai

$$\frac{12}{x}$$

Ngā Upane Otinga

Whakawehe \frac{16x^{2}}{7} ki te \frac{4x^{3}}{21} mā te whakarea \frac{16x^{2}}{7} ki te tau huripoki o \frac{4x^{3}}{21}.

$$\frac{16x^{2}\times 21}{7\times 4x^{3}}$$

Me whakakore tahi te 4\times 7x^{2} i te taurunga me te tauraro.

$$\frac{3\times 4}{x}$$

Whakareatia te 3 ki te 4, ka 12.

$$\frac{12}{x}$$

Kimi Pārōnaki e ai ki x

$$-\frac{12}{x^{2}}$$

Ngā Upane e Whakamahi ana i te Tautuhinga o te Pārōnaki

Whakawehe \frac{16x^{2}}{7} ki te \frac{4x^{3}}{21} mā te whakarea \frac{16x^{2}}{7} ki te tau huripoki o \frac{4x^{3}}{21}.

$$\frac{\mathrm{d}}{\mathrm{d}x}(\frac{16x^{2}\times 21}{7\times 4x^{3}})$$

Me whakakore tahi te 4\times 7x^{2} i te taurunga me te tauraro.

$$\frac{\mathrm{d}}{\mathrm{d}x}(\frac{3\times 4}{x})$$

Whakareatia te 3 ki te 4, ka 12.

$$\frac{\mathrm{d}}{\mathrm{d}x}(\frac{12}{x})$$

Ko te pārōnaki o ax^{n} ko nax^{n-1}.

$$-12x^{-1-1}$$

Tango 1 mai i -1.

$$-12x^{-2}$$
