$$\frac{3a^{22}}{128}$$

Ngā Upane Otinga

Hei whakarea i ngā pū o te pūtake kotahi, me tāpiri ō rātou taupū. Tāpiria te -8 me te 30 kia riro ai te 22.

$$\left(\frac{81}{16}\right)^{0.25}\left(-8\right)^{-\frac{4}{3}}a^{22}\times 2^{-2}$$

Tātaihia te \frac{81}{16} mā te pū o 0.25, kia riro ko \frac{3}{2}.

$$\frac{3}{2}\left(-8\right)^{-\frac{4}{3}}a^{22}\times 2^{-2}$$

Tātaihia te -8 mā te pū o -\frac{4}{3}, kia riro ko \frac{1}{16}.

$$\frac{3}{2}\times \frac{1}{16}a^{22}\times 2^{-2}$$

Whakareatia te \frac{3}{2} ki te \frac{1}{16}, ka \frac{3}{32}.

$$\frac{3}{32}a^{22}\times 2^{-2}$$

Tātaihia te 2 mā te pū o -2, kia riro ko \frac{1}{4}.

$$\frac{3}{32}a^{22}\times \frac{1}{4}$$

Whakareatia te \frac{3}{32} ki te \frac{1}{4}, ka \frac{3}{128}.

$$\frac{3}{128}a^{22}$$

Kimi Pārōnaki e ai ki a

$$\frac{33a^{21}}{64}$$

Ngā Upane e Whakamahi ana i te Tautuhinga o te Pārōnaki

Hei whakarea i ngā pū o te pūtake kotahi, me tāpiri ō rātou taupū. Tāpiria te -8 me te 30 kia riro ai te 22.

$$\frac{\mathrm{d}}{\mathrm{d}a}(\left(\frac{81}{16}\right)^{0.25}\left(-8\right)^{-\frac{4}{3}}a^{22}\times 2^{-2})$$

Tātaihia te \frac{81}{16} mā te pū o 0.25, kia riro ko \frac{3}{2}.

$$\frac{\mathrm{d}}{\mathrm{d}a}(\frac{3}{2}\left(-8\right)^{-\frac{4}{3}}a^{22}\times 2^{-2})$$

Tātaihia te -8 mā te pū o -\frac{4}{3}, kia riro ko \frac{1}{16}.

$$\frac{\mathrm{d}}{\mathrm{d}a}(\frac{3}{2}\times \frac{1}{16}a^{22}\times 2^{-2})$$

Whakareatia te \frac{3}{2} ki te \frac{1}{16}, ka \frac{3}{32}.

$$\frac{\mathrm{d}}{\mathrm{d}a}(\frac{3}{32}a^{22}\times 2^{-2})$$

Tātaihia te 2 mā te pū o -2, kia riro ko \frac{1}{4}.

$$\frac{\mathrm{d}}{\mathrm{d}a}(\frac{3}{32}a^{22}\times \frac{1}{4})$$

Whakareatia te \frac{3}{32} ki te \frac{1}{4}, ka \frac{3}{128}.

$$\frac{\mathrm{d}}{\mathrm{d}a}(\frac{3}{128}a^{22})$$

Ko te pārōnaki o ax^{n} ko nax^{n-1}.

$$22\times \frac{3}{128}a^{22-1}$$

Whakareatia 22 ki te \frac{3}{128}.

$$\frac{33}{64}a^{22-1}$$

Tango 1 mai i 22.
