Yechim qadamlari

-2 ning teskarisi 2 ga teng.

$$2\times 4^{3}-7\left(-2\right)^{3}-4^{3}$$

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

$$2\times 64-7\left(-2\right)^{3}-4^{3}$$

128 hosil qilish uchun 2 va 64 ni ko'paytirish.

$$128-7\left(-2\right)^{3}-4^{3}$$

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

$$128-7\left(-8\right)-4^{3}$$

-56 hosil qilish uchun 7 va -8 ni ko'paytirish.

$$128-\left(-56\right)-4^{3}$$

-56 ning teskarisi 56 ga teng.

$$128+56-4^{3}$$

184 olish uchun 128 va 56'ni qo'shing.

$$184-4^{3}$$

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

$$184-64$$

120 olish uchun 184 dan 64 ni ayirish.

$$120$$

Omil

$$2^{3}\times 3\times 5$$
