Yechim qadamlari

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

$$\frac{100}{4}-\frac{-2}{-\frac{2}{3}}+\left(-2\right)^{3}$$

25 ni olish uchun 100 ni 4 ga bo‘ling.

$$25-\frac{-2}{-\frac{2}{3}}+\left(-2\right)^{3}$$

-2 ni -\frac{2}{3} ga bo'lish -2 ga k'paytirish -\frac{2}{3} ga qaytarish.

$$25-\left(-2\left(-\frac{3}{2}\right)\right)+\left(-2\right)^{3}$$

-2 ni -\frac{3}{2} marotabaga ko'paytirish.

$$25-3+\left(-2\right)^{3}$$

22 olish uchun 25 dan 3 ni ayirish.

$$22+\left(-2\right)^{3}$$

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

$$22-8$$

14 olish uchun 22 dan 8 ni ayirish.
