$$\frac { 4 y ^ { 4 } x ^ { - 8 } } { 8 x ^ { - 7 } y ^ { - 2 } }$$

Baholash

$$\frac{y^{6}}{2x}$$

Yechim qadamlari

Surat va maxrajdagi ikkala 4 ni qisqartiring.

$$\frac{x^{-8}y^{4}}{2x^{-7}y^{-2}}$$

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

$$\frac{x^{-8}y^{6}}{2x^{-7}}$$

Ayni asosning daraja ko‘rsatkichini bo‘lish uchun suratning darajasini maxraj darajasiga bo‘ling.

$$\frac{y^{6}}{2x^{1}}$$

1 daraja ko‘rsatkichini x ga hisoblang va x ni qiymatni oling.

$$\frac{y^{6}}{2x}$$

x ga nisbatan hosilani topish

$$-\frac{y^{6}}{2x^{2}}$$
