Yechim qadamlari

7 olish uchun 5 va 2'ni qo'shing.

$$8\times 7-\frac{\frac{27}{3}}{27}+2^{3}+\frac{4}{2}$$

56 hosil qilish uchun 8 va 7 ni ko'paytirish.

$$56-\frac{\frac{27}{3}}{27}+2^{3}+\frac{4}{2}$$

\frac{\frac{27}{3}}{27} ni yagona kasrga aylantiring.

$$56-\frac{27}{3\times 27}+2^{3}+\frac{4}{2}$$

81 hosil qilish uchun 3 va 27 ni ko'paytirish.

$$56-\frac{27}{81}+2^{3}+\frac{4}{2}$$

\frac{27}{81} ulushini 27 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$56-\frac{1}{3}+2^{3}+\frac{4}{2}$$

56 ni \frac{168}{3} kasrga o‘giring.

$$\frac{168}{3}-\frac{1}{3}+2^{3}+\frac{4}{2}$$

\frac{168}{3} va \frac{1}{3} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{168-1}{3}+2^{3}+\frac{4}{2}$$

167 olish uchun 168 dan 1 ni ayirish.

$$\frac{167}{3}+2^{3}+\frac{4}{2}$$

3 daraja ko‘rsatkichini 2 ga hisoblang va 8 ni qiymatni oling.

$$\frac{167}{3}+8+\frac{4}{2}$$

8 ni \frac{24}{3} kasrga o‘giring.

$$\frac{167}{3}+\frac{24}{3}+\frac{4}{2}$$

\frac{167}{3} va \frac{24}{3} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{167+24}{3}+\frac{4}{2}$$

191 olish uchun 167 va 24'ni qo'shing.

$$\frac{191}{3}+\frac{4}{2}$$

2 ni olish uchun 4 ni 2 ga bo‘ling.

$$\frac{191}{3}+2$$

2 ni \frac{6}{3} kasrga o‘giring.

$$\frac{191}{3}+\frac{6}{3}$$

\frac{191}{3} va \frac{6}{3} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{191+6}{3}$$

197 olish uchun 191 va 6'ni qo'shing.

$$\frac{197}{3}$$

Omil

$$\frac{197}{3} = 65\frac{2}{3} = 65,66666666666667$$
