Yechim qadamlari

4 daraja ko‘rsatkichini -3 ga hisoblang va 81 ni qiymatni oling.

$$81+2\left(-3\right)^{3}-9\left(-3\right)^{2}-2\left(-3\right)+9$$

3 daraja ko‘rsatkichini -3 ga hisoblang va -27 ni qiymatni oling.

$$81+2\left(-27\right)-9\left(-3\right)^{2}-2\left(-3\right)+9$$

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

$$81-54-9\left(-3\right)^{2}-2\left(-3\right)+9$$

27 olish uchun 81 dan 54 ni ayirish.

$$27-9\left(-3\right)^{2}-2\left(-3\right)+9$$

2 daraja ko‘rsatkichini -3 ga hisoblang va 9 ni qiymatni oling.

$$27-9\times 9-2\left(-3\right)+9$$

81 hosil qilish uchun 9 va 9 ni ko'paytirish.

$$27-81-2\left(-3\right)+9$$

-54 olish uchun 27 dan 81 ni ayirish.

$$-54-2\left(-3\right)+9$$
