Yechim qadamlari

2 daraja ko‘rsatkichini 3 ga hisoblang va 9 ni qiymatni oling.

$$9+2^{2}-\frac{12}{5+4}$$

2 daraja ko‘rsatkichini 2 ga hisoblang va 4 ni qiymatni oling.

$$9+4-\frac{12}{5+4}$$

13 olish uchun 9 va 4'ni qo'shing.

$$13-\frac{12}{5+4}$$

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

$$13-\frac{12}{9}$$

\frac{12}{9} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$13-\frac{4}{3}$$

13 ni \frac{39}{3} kasrga o‘giring.

$$\frac{39}{3}-\frac{4}{3}$$

\frac{39}{3} va \frac{4}{3} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{39-4}{3}$$

35 olish uchun 39 dan 4 ni ayirish.

$$\frac{35}{3}$$

Omil

$$\frac{5 \cdot 7}{3} = 11\frac{2}{3} = 11,666666666666666$$
