$$\frac{475}{8}=59,375$$

Yechim qadamlari

4 daraja ko‘rsatkichini 5 ga hisoblang va 625 ni qiymatni oling.

$$\frac{625}{8}-\frac{5^{3}}{4}+\frac{5^{2}}{2}$$

3 daraja ko‘rsatkichini 5 ga hisoblang va 125 ni qiymatni oling.

$$\frac{625}{8}-\frac{125}{4}+\frac{5^{2}}{2}$$

8 va 4 ning eng kichik umumiy karralisi 8 ga teng. \frac{625}{8} va \frac{125}{4} ni 8 maxraj bilan kasrlarga aylantirib oling.

$$\frac{625}{8}-\frac{250}{8}+\frac{5^{2}}{2}$$

\frac{625}{8} va \frac{250}{8} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{625-250}{8}+\frac{5^{2}}{2}$$

375 olish uchun 625 dan 250 ni ayirish.

$$\frac{375}{8}+\frac{5^{2}}{2}$$

2 daraja ko‘rsatkichini 5 ga hisoblang va 25 ni qiymatni oling.

$$\frac{375}{8}+\frac{25}{2}$$

8 va 2 ning eng kichik umumiy karralisi 8 ga teng. \frac{375}{8} va \frac{25}{2} ni 8 maxraj bilan kasrlarga aylantirib oling.

$$\frac{375}{8}+\frac{100}{8}$$

\frac{375}{8} va \frac{100}{8} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{375+100}{8}$$

475 olish uchun 375 va 100'ni qo'shing.

$$\frac{475}{8}$$

Omil

$$\frac{5 ^ {2} \cdot 19}{2 ^ {3}} = 59\frac{3}{8} = 59,375$$
