Yechim qadamlari

Ayni asosning daraja ko‘rsatkichlarini ko‘paytirish uchun ularning darajalarini qo‘shing. 5 va 8 ni qo‘shib, 13 ni oling.

$$\frac{-\frac{3}{7}x^{13}z^{8}}{-\frac{1}{14}x^{5}y^{6}z^{6}}$$

Surat va maxrajdagi ikkala x^{5}z^{6} ni qisqartiring.

$$\frac{-\frac{3}{7}z^{2}x^{8}}{-\frac{1}{14}y^{6}}$$

x ga nisbatan hosilani topish

$$\frac{48z^{2}x^{7}}{y^{6}}$$

Yechim qadamlari

Ayni asosning daraja ko'rsatkichi bo'lish uchun maxrajning darajasini surat darajasidan bo'ling.

$$\frac{\mathrm{d}}{\mathrm{d}x}(\left(-\frac{\frac{3x^{8}z^{8}}{7}}{-\frac{y^{6}z^{6}}{14}}\right)x^{5-5})$$

Arifmetik hisobni amalga oshirish.

$$\frac{\mathrm{d}}{\mathrm{d}x}(\frac{6z^{2}x^{8}}{y^{6}}x^{0})$$

Har qanday a raqami uchun (0 bundan mustasno) a^{0}=1.

$$\frac{\mathrm{d}}{\mathrm{d}x}(\frac{6z^{2}x^{8}}{y^{6}})$$

Konstantaning hosilasi 0 ga teng.
