Yechim qadamlari

Ayni asosning daraja ko‘rsatkichlarini ko‘paytirish uchun ularning darajalarini qo‘shing. -3 va -4 ni qo‘shib, -7 ni oling.

$$2\times 10^{-7}\times 5$$

-7 daraja ko‘rsatkichini 10 ga hisoblang va \frac{1}{10000000} ni qiymatni oling.

$$2\times \frac{1}{10000000}\times 5$$

\frac{1}{5000000} hosil qilish uchun 2 va \frac{1}{10000000} ni ko'paytirish.

$$\frac{1}{5000000}\times 5$$

\frac{1}{1000000} hosil qilish uchun \frac{1}{5000000} va 5 ni ko'paytirish.

$$\frac{1}{1000000}$$

Omil

$$\frac{1}{2 ^ {6} \cdot 5 ^ {6}} = 1 \times 10^{-6}$$
