4^3(-12+2^3)/5(2)^2 eching

$$\frac { 4 ^ { 3 } ( - 12 + 2 ^ { 3 } ) } { 5 ( 2 ) ^ { 2 } }$$

Baholash

$$-\frac{64}{5}=-12,8$$

Yechim qadamlari

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

$$\frac{64\left(-12+2^{3}\right)}{5\times 2^{2}}$$

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

$$\frac{64\left(-12+8\right)}{5\times 2^{2}}$$

-4 olish uchun -12 va 8'ni qo'shing.

$$\frac{64\left(-4\right)}{5\times 2^{2}}$$

-256 hosil qilish uchun 64 va -4 ni ko'paytirish.

$$\frac{-256}{5\times 2^{2}}$$

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

$$\frac{-256}{5\times 4}$$

20 hosil qilish uchun 5 va 4 ni ko'paytirish.

$$\frac{-256}{20}$$

\frac{-256}{20} ulushini 4 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$-\frac{64}{5}$$

Omil

$$-\frac{64}{5} = -12\frac{4}{5} = -12,8$$
