Yechim qadamlari

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

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

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

$$8-2^{3}+3\times 2-5$$

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