Yechim qadamlari

Ayni asosning daraja ko‘rsatkichlarini ko‘paytirish uchun ularning darajalarini qo‘shing. -5 va -8 ni qo‘shib, -13 ni oling.

$$240\times 10^{-13}\times 100$$

-13 daraja ko‘rsatkichini 10 ga hisoblang va \frac{1}{10000000000000} ni qiymatni oling.

$$240\times \frac{1}{10000000000000}\times 100$$

\frac{3}{125000000000} hosil qilish uchun 240 va \frac{1}{10000000000000} ni ko'paytirish.

$$\frac{3}{125000000000}\times 100$$

\frac{3}{1250000000} hosil qilish uchun \frac{3}{125000000000} va 100 ni ko'paytirish.

$$\frac{3}{1250000000}$$

Omil

$$\frac{3}{2 ^ {7} \cdot 5 ^ {10}} = 2,4 \times 10^{-9}$$
