(-5)^3:(-2)+3*(-4^3) eching

$$( - 5 ) ^ { 3 } : ( - 2 ) + 3 \cdot ( - 4 ^ { 3 } )$$

Baholash

$$-\frac{259}{2}=-129,5$$

Yechim qadamlari

3 daraja ko‘rsatkichini -5 ga hisoblang va -125 ni qiymatni oling.

$$\frac{-125}{-2}+3\left(-4^{3}\right)$$

Ikkala surat va maxrajdan manfiy belgini olib tashlash bilan \frac{-125}{-2} kasrini \frac{125}{2} ga soddalashtirish mumkin.

$$\frac{125}{2}+3\left(-4^{3}\right)$$

3 daraja ko‘rsatkichini 4 ga hisoblang va 64 ni qiymatni oling.

$$\frac{125}{2}+3\left(-64\right)$$

-192 hosil qilish uchun 3 va -64 ni ko'paytirish.

$$\frac{125}{2}-192$$

192 ni \frac{384}{2} kasrga o‘giring.

$$\frac{125}{2}-\frac{384}{2}$$

\frac{125}{2} va \frac{384}{2} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{125-384}{2}$$

-259 olish uchun 125 dan 384 ni ayirish.

$$-\frac{259}{2}$$

Omil

$$-\frac{259}{2} = -129\frac{1}{2} = -129,5$$
