Yechim qadamlari

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

$$-9\left(-\frac{1}{3}\right)^{2}+\left(\frac{3}{4}-\frac{1}{6}+\frac{3}{8}\right)\left(-24\right)$$

2 daraja ko‘rsatkichini -\frac{1}{3} ga hisoblang va \frac{1}{9} ni qiymatni oling.

$$-9\times \frac{1}{9}+\left(\frac{3}{4}-\frac{1}{6}+\frac{3}{8}\right)\left(-24\right)$$

-9 ni \frac{1}{9} marotabaga ko'paytirish.

$$-1+\left(\frac{3}{4}-\frac{1}{6}+\frac{3}{8}\right)\left(-24\right)$$

4 va 6 ning eng kichik umumiy karralisi 12 ga teng. \frac{3}{4} va \frac{1}{6} ni 12 maxraj bilan kasrlarga aylantirib oling.

$$-1+\left(\frac{9}{12}-\frac{2}{12}+\frac{3}{8}\right)\left(-24\right)$$

\frac{9}{12} va \frac{2}{12} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$-1+\left(\frac{9-2}{12}+\frac{3}{8}\right)\left(-24\right)$$

7 olish uchun 9 dan 2 ni ayirish.

$$-1+\left(\frac{7}{12}+\frac{3}{8}\right)\left(-24\right)$$

12 va 8 ning eng kichik umumiy karralisi 24 ga teng. \frac{7}{12} va \frac{3}{8} ni 24 maxraj bilan kasrlarga aylantirib oling.

$$-1+\left(\frac{14}{24}+\frac{9}{24}\right)\left(-24\right)$$

\frac{14}{24} va \frac{9}{24} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$-1+\frac{14+9}{24}\left(-24\right)$$

23 olish uchun 14 va 9'ni qo'shing.

$$-1+\frac{23}{24}\left(-24\right)$$

\frac{23}{24}\left(-24\right) ni yagona kasrga aylantiring.

$$-1+\frac{23\left(-24\right)}{24}$$

-552 hosil qilish uchun 23 va -24 ni ko'paytirish.

$$-1+\frac{-552}{24}$$

-23 ni olish uchun -552 ni 24 ga bo‘ling.

$$-1-23$$

-24 olish uchun -1 dan 23 ni ayirish.

$$-24$$
