-2^3/3+1/-2(-2^2) eching

$$\frac{ - { 2 }^{ 3 } }{ 3 } + \frac{ 1 }{ -2(- { 2 }^{ 2 } ) }$$

$$-\frac{61}{24}\approx -2,541666667$$

Yechim qadamlari

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

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

\frac{-8}{3} kasri manfiy belgini olib tashlash bilan -\frac{8}{3} sifatida qayta yozilishi mumkin.

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

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

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

8 hosil qilish uchun -2 va -4 ni ko'paytirish.

$$-\frac{8}{3}+\frac{1}{8}$$

3 va 8 ning eng kichik umumiy karralisi 24 ga teng. -\frac{8}{3} va \frac{1}{8} ni 24 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{64}{24}+\frac{3}{24}$$

-\frac{64}{24} va \frac{3}{24} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-64+3}{24}$$

-61 olish uchun -64 va 3'ni qo'shing.

$$-\frac{61}{24}$$

Omil

$$-\frac{61}{24} = -2\frac{13}{24} = -2,5416666666666665$$
