Yechim qadamlari

Ayni asosning daraja ko‘rsatkichlarini ko‘paytirish uchun ularning darajalarini qo‘shing. -5 va 4 ni qo‘shib, -1 ni oling.

$$2^{-1}-2^{-3}$$

-1 daraja ko‘rsatkichini 2 ga hisoblang va \frac{1}{2} ni qiymatni oling.

$$\frac{1}{2}-2^{-3}$$

-3 daraja ko‘rsatkichini 2 ga hisoblang va \frac{1}{8} ni qiymatni oling.

$$\frac{1}{2}-\frac{1}{8}$$

\frac{3}{8} olish uchun \frac{1}{2} dan \frac{1}{8} ni ayirish.

$$\frac{3}{8}$$

Omil

$$\frac{3}{2 ^ {3}} = 0,375$$
