$$\frac{5}{8}=0,625$$

Yechim qadamlari

3 daraja ko‘rsatkichini -\frac{1}{2} ga hisoblang va -\frac{1}{8} ni qiymatni oling.

$$\frac{1}{2}-\left(-\frac{1}{8}\right)$$

-\frac{1}{8} ning teskarisi \frac{1}{8} ga teng.

$$\frac{1}{2}+\frac{1}{8}$$

2 va 8 ning eng kichik umumiy karralisi 8 ga teng. \frac{1}{2} va \frac{1}{8} ni 8 maxraj bilan kasrlarga aylantirib oling.

$$\frac{4}{8}+\frac{1}{8}$$

\frac{4}{8} va \frac{1}{8} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{4+1}{8}$$

5 olish uchun 4 va 1'ni qo'shing.

$$\frac{5}{8}$$

Omil

$$\frac{5}{2 ^ {3}} = 0,625$$
