Yechim qadamlari

4 daraja ko‘rsatkichini -2 ga hisoblang va 16 ni qiymatni oling.

$$16\times 16-12\left(-2\right)^{2}-27\left(-2\right)$$

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

$$256-12\left(-2\right)^{2}-27\left(-2\right)$$

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

$$256-12\times 4-27\left(-2\right)$$

48 hosil qilish uchun 12 va 4 ni ko'paytirish.

$$256-48-27\left(-2\right)$$

208 olish uchun 256 dan 48 ni ayirish.

$$208-27\left(-2\right)$$

-54 hosil qilish uchun 27 va -2 ni ko'paytirish.

$$208-\left(-54\right)$$

-54 ning teskarisi 54 ga teng.

$$208+54$$

262 olish uchun 208 va 54'ni qo'shing.

$$262$$
