Yechim qadamlari

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

$$23\times \frac{1}{100}+27\times 10^{-1}$$

\frac{23}{100} hosil qilish uchun 23 va \frac{1}{100} ni ko'paytirish.

$$\frac{23}{100}+27\times 10^{-1}$$

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

$$\frac{23}{100}+27\times \frac{1}{10}$$

\frac{27}{10} hosil qilish uchun 27 va \frac{1}{10} ni ko'paytirish.

$$\frac{23}{100}+\frac{27}{10}$$

\frac{293}{100} olish uchun \frac{23}{100} va \frac{27}{10}'ni qo'shing.

$$\frac{293}{100}$$

Omil

$$\frac{293}{2 ^ {2} \cdot 5 ^ {2}} = 2\frac{93}{100} = 2,93$$
