8^-1*5^-1/2^-4 eching

$$\frac { 8 ^ { - 1 } \times 5 ^ { - 1 } } { 2 ^ { - 4 } }$$

Baholash

$$\frac{2}{5}=0,4$$

Yechim qadamlari

-1 daraja ko‘rsatkichini 8 ga hisoblang va \frac{1}{8} ni qiymatni oling.

$$\frac{\frac{1}{8}\times 5^{-1}}{2^{-4}}$$

-1 daraja ko‘rsatkichini 5 ga hisoblang va \frac{1}{5} ni qiymatni oling.

$$\frac{\frac{1}{8}\times \frac{1}{5}}{2^{-4}}$$

\frac{1}{40} hosil qilish uchun \frac{1}{8} va \frac{1}{5} ni ko'paytirish.

$$\frac{\frac{1}{40}}{2^{-4}}$$

-4 daraja ko‘rsatkichini 2 ga hisoblang va \frac{1}{16} ni qiymatni oling.

$$\frac{\frac{1}{40}}{\frac{1}{16}}$$

\frac{1}{40} ni \frac{1}{16} ga bo'lish \frac{1}{40} ga k'paytirish \frac{1}{16} ga qaytarish.

$$\frac{1}{40}\times 16$$

\frac{2}{5} hosil qilish uchun \frac{1}{40} va 16 ni ko'paytirish.

$$\frac{2}{5}$$

Omil

$$\frac{2}{5} = 0,4$$
