Yechim qadamlari

Ayni asosning daraja ko‘rsatkichlarini ko‘paytirish uchun ularning darajalarini qo‘shing. 8 va -12 ni qo‘shib, -4 ni oling.

$$138\times 10^{-4}\times 54$$

-4 daraja ko‘rsatkichini 10 ga hisoblang va \frac{1}{10000} ni qiymatni oling.

$$138\times \frac{1}{10000}\times 54$$

\frac{69}{5000} hosil qilish uchun 138 va \frac{1}{10000} ni ko'paytirish.

$$\frac{69}{5000}\times 54$$

\frac{1863}{2500} hosil qilish uchun \frac{69}{5000} va 54 ni ko'paytirish.

$$\frac{1863}{2500}$$

Omil

$$\frac{3 ^ {4} \cdot 23}{2 ^ {2} \cdot 5 ^ {4}} = 0,7452$$
