-1/3*(10-2^2)-15*1/2= eching

$$- \frac { 1 } { 3 } \cdot ( 10 - 2 ^ { 2 } ) - 15 \cdot \frac { 1 } { 2 } =$$

Baholash

$$-\frac{19}{2}=-9,5$$

Yechim qadamlari

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

$$-\frac{1}{3}\left(10-4\right)-15\times \frac{1}{2}$$

6 olish uchun 10 dan 4 ni ayirish.

$$-\frac{1}{3}\times 6-15\times \frac{1}{2}$$

-\frac{1}{3}\times 6 ni yagona kasrga aylantiring.

$$\frac{-6}{3}-15\times \frac{1}{2}$$

-2 ni olish uchun -6 ni 3 ga bo‘ling.

$$-2-15\times \frac{1}{2}$$

\frac{15}{2} hosil qilish uchun 15 va \frac{1}{2} ni ko'paytirish.

$$-2-\frac{15}{2}$$

-2 ni -\frac{4}{2} kasrga o‘giring.

$$-\frac{4}{2}-\frac{15}{2}$$

-\frac{4}{2} va \frac{15}{2} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{-4-15}{2}$$

-19 olish uchun -4 dan 15 ni ayirish.

$$-\frac{19}{2}$$

Omil

$$-\frac{19}{2} = -9\frac{1}{2} = -9,5$$
