Yechim qadamlari

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

$$81-3^{2}+\left(-\frac{1}{3}\right)^{-3}$$

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

$$81-9+\left(-\frac{1}{3}\right)^{-3}$$

72 olish uchun 81 dan 9 ni ayirish.

$$72+\left(-\frac{1}{3}\right)^{-3}$$

-3 daraja ko‘rsatkichini -\frac{1}{3} ga hisoblang va -27 ni qiymatni oling.

$$72-27$$

45 olish uchun 72 dan 27 ni ayirish.

$$45$$
