$$52 \times 10 ^ { - 2 } + 42 \times 10 ^ { - 3 }$$

Baholash

$$\frac{281}{500}=0,562$$

Yechim qadamlari

-2 daraja ko‘rsatkichini 10 ga hisoblang va \frac{1}{100} ni qiymatni oling.

$$52\times \frac{1}{100}+42\times 10^{-3}$$

\frac{13}{25} hosil qilish uchun 52 va \frac{1}{100} ni ko'paytirish.

$$\frac{13}{25}+42\times 10^{-3}$$

-3 daraja ko‘rsatkichini 10 ga hisoblang va \frac{1}{1000} ni qiymatni oling.

$$\frac{13}{25}+42\times \frac{1}{1000}$$

\frac{21}{500} hosil qilish uchun 42 va \frac{1}{1000} ni ko'paytirish.

$$\frac{13}{25}+\frac{21}{500}$$

\frac{281}{500} olish uchun \frac{13}{25} va \frac{21}{500}'ni qo'shing.

$$\frac{281}{500}$$

Omil

$$\frac{281}{2 ^ {2} \cdot 5 ^ {3}} = 0,562$$
