Yechim qadamlari

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

$$\frac{1}{4}+\frac{32^{-3}}{\frac{5}{8}}-0\times 4$$

-3 daraja ko‘rsatkichini 32 ga hisoblang va \frac{1}{32768} ni qiymatni oling.

$$\frac{1}{4}+\frac{\frac{1}{32768}}{\frac{5}{8}}-0\times 4$$

\frac{1}{32768} ni \frac{5}{8} ga bo'lish \frac{1}{32768} ga k'paytirish \frac{5}{8} ga qaytarish.

$$\frac{1}{4}+\frac{1}{32768}\times \frac{8}{5}-0\times 4$$

\frac{1}{20480} hosil qilish uchun \frac{1}{32768} va \frac{8}{5} ni ko'paytirish.
