Yechim qadamlari

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

$$\frac{3^{-2}z^{3}b^{6}}{2^{-2}}$$

-2 daraja ko‘rsatkichini 3 ga hisoblang va \frac{1}{9} ni qiymatni oling.

$$\frac{\frac{1}{9}z^{3}b^{6}}{2^{-2}}$$

-2 daraja ko‘rsatkichini 2 ga hisoblang va \frac{1}{4} ni qiymatni oling.

$$\frac{\frac{1}{9}z^{3}b^{6}}{\frac{1}{4}}$$

\frac{1}{9}z^{3}b^{6} ni \frac{1}{4} ga bo'lish \frac{1}{9}z^{3}b^{6} ga k'paytirish \frac{1}{4} ga qaytarish.

$$\frac{1}{9}z^{3}b^{6}\times 4$$

\frac{4}{9} hosil qilish uchun \frac{1}{9} va 4 ni ko'paytirish.

$$\frac{4}{9}z^{3}b^{6}$$

b ga nisbatan hosilani topish

$$\frac{8z^{3}b^{5}}{3}$$
