Yechim qadamlari

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

$$-4\left(-\frac{1}{2}\right)+\frac{8}{\left(-2\right)^{2}}$$

-4\left(-\frac{1}{2}\right) ni yagona kasrga aylantiring.

$$\frac{-4\left(-1\right)}{2}+\frac{8}{\left(-2\right)^{2}}$$

4 hosil qilish uchun -4 va -1 ni ko'paytirish.

$$\frac{4}{2}+\frac{8}{\left(-2\right)^{2}}$$

2 ni olish uchun 4 ni 2 ga bo‘ling.

$$2+\frac{8}{\left(-2\right)^{2}}$$

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

$$2+\frac{8}{4}$$

2 ni olish uchun 8 ni 4 ga bo‘ling.

$$2+2$$

4 olish uchun 2 va 2'ni qo'shing.
