Yechim qadamlari

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

$$-\frac{1}{2}-8\times 3^{2}+3-2^{2}\times 4^{2}$$

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

$$-\frac{1}{2}-8\times 9+3-2^{2}\times 4^{2}$$

72 hosil qilish uchun 8 va 9 ni ko'paytirish.

$$-\frac{1}{2}-72+3-2^{2}\times 4^{2}$$

72 ni \frac{144}{2} kasrga o‘giring.

$$-\frac{1}{2}-\frac{144}{2}+3-2^{2}\times 4^{2}$$

-\frac{1}{2} va \frac{144}{2} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{-1-144}{2}+3-2^{2}\times 4^{2}$$

-145 olish uchun -1 dan 144 ni ayirish.

$$-\frac{145}{2}+3-2^{2}\times 4^{2}$$

3 ni \frac{6}{2} kasrga o‘giring.

$$-\frac{145}{2}+\frac{6}{2}-2^{2}\times 4^{2}$$

-\frac{145}{2} va \frac{6}{2} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-145+6}{2}-2^{2}\times 4^{2}$$

-139 olish uchun -145 va 6'ni qo'shing.

$$-\frac{139}{2}-2^{2}\times 4^{2}$$

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

$$-\frac{139}{2}-4\times 4^{2}$$

2 daraja ko‘rsatkichini 4 ga hisoblang va 16 ni qiymatni oling.

$$-\frac{139}{2}-4\times 16$$

64 hosil qilish uchun 4 va 16 ni ko'paytirish.

$$-\frac{139}{2}-64$$

64 ni \frac{128}{2} kasrga o‘giring.

$$-\frac{139}{2}-\frac{128}{2}$$

-\frac{139}{2} va \frac{128}{2} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{-139-128}{2}$$

-267 olish uchun -139 dan 128 ni ayirish.

$$-\frac{267}{2}$$

Omil

$$-\frac{267}{2} = -133\frac{1}{2} = -133,5$$
