1/2-2^3*3^2+3-2^2*4 eching

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

Baholash

$$-\frac{169}{2}=-84,5$$

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

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

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

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

72 ni \frac{144}{2} kasrga o‘giring.

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

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

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

-143 olish uchun 1 dan 144 ni ayirish.

$$-\frac{143}{2}+3-2^{2}\times 4$$

3 ni \frac{6}{2} kasrga o‘giring.

$$-\frac{143}{2}+\frac{6}{2}-2^{2}\times 4$$

-\frac{143}{2} va \frac{6}{2} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-143+6}{2}-2^{2}\times 4$$

-137 olish uchun -143 va 6'ni qo'shing.

$$-\frac{137}{2}-2^{2}\times 4$$

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

$$-\frac{137}{2}-4\times 4$$

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

$$-\frac{137}{2}-16$$

16 ni \frac{32}{2} kasrga o‘giring.

$$-\frac{137}{2}-\frac{32}{2}$$

-\frac{137}{2} va \frac{32}{2} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{-137-32}{2}$$

-169 olish uchun -137 dan 32 ni ayirish.

$$-\frac{169}{2}$$

Omil

$$-\frac{169}{2} = -84\frac{1}{2} = -84,5$$
