Yechim qadamlari

Ayni asosning daraja ko‘rsatkichlarini ko‘paytirish uchun ularning darajalarini qo‘shing. 8 va 7 ni qo‘shib, 15 ni oling.

$$2\times 10^{15}\times 2\times 5$$

15 daraja ko‘rsatkichini 10 ga hisoblang va 1000000000000000 ni qiymatni oling.

$$2\times 1000000000000000\times 2\times 5$$
