Yechim qadamlari

-1 daraja ko‘rsatkichini 6 ga hisoblang va \frac{1}{6} ni qiymatni oling.

$$\frac{\frac{2}{3}}{\frac{1}{6}+7^{0}}$$

0 daraja ko‘rsatkichini 7 ga hisoblang va 1 ni qiymatni oling.

$$\frac{\frac{2}{3}}{\frac{1}{6}+1}$$

\frac{7}{6} olish uchun \frac{1}{6} va 1'ni qo'shing.

$$\frac{\frac{2}{3}}{\frac{7}{6}}$$

\frac{2}{3} ni \frac{7}{6} ga bo'lish \frac{2}{3} ga k'paytirish \frac{7}{6} ga qaytarish.

$$\frac{2}{3}\times \frac{6}{7}$$

\frac{4}{7} hosil qilish uchun \frac{2}{3} va \frac{6}{7} ni ko'paytirish.
