Yechim qadamlari

Ayni asosning daraja ko‘rsatkichini bo‘lish uchun maxrajning darajasini surat darajasidan ayiring. 5 dan 3 ni ayirib, 2 ni oling.

$$5^{2}\times 5^{-3}$$

Ayni asosning daraja ko‘rsatkichlarini ko‘paytirish uchun ularning darajalarini qo‘shing. 2 va -3 ni qo‘shib, -1 ni oling.

$$5^{-1}$$

-1 daraja ko‘rsatkichini 5 ga hisoblang va \frac{1}{5} ni qiymatni oling.

$$\frac{1}{5}$$

Omil

$$\frac{1}{5} = 0,2$$
