Yechim qadamlari

2 daraja ko‘rsatkichini \frac{3}{2} ga hisoblang va \frac{9}{4} ni qiymatni oling.

$$\frac{9}{4}+3\times \frac{3}{2}-2$$

3\times \frac{3}{2} ni yagona kasrga aylantiring.

$$\frac{9}{4}+\frac{3\times 3}{2}-2$$

9 hosil qilish uchun 3 va 3 ni ko'paytirish.

$$\frac{9}{4}+\frac{9}{2}-2$$

4 va 2 ning eng kichik umumiy karralisi 4 ga teng. \frac{9}{4} va \frac{9}{2} ni 4 maxraj bilan kasrlarga aylantirib oling.

$$\frac{9}{4}+\frac{18}{4}-2$$

\frac{9}{4} va \frac{18}{4} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{9+18}{4}-2$$

27 olish uchun 9 va 18'ni qo'shing.

$$\frac{27}{4}-2$$

2 ni \frac{8}{4} kasrga o‘giring.

$$\frac{27}{4}-\frac{8}{4}$$

\frac{27}{4} va \frac{8}{4} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{27-8}{4}$$

19 olish uchun 27 dan 8 ni ayirish.

$$\frac{19}{4}$$

Omil

$$\frac{19}{2 ^ {2}} = 4\frac{3}{4} = 4,75$$
