Baholash

$$\frac{4}{5}=0,8$$

Yechim qadamlari

\frac{2}{3} olish uchun 1 dan \frac{1}{3} ni ayirish.

$$\frac{\left(\frac{2}{3}\right)^{2}+1-\frac{1}{9}}{2-\frac{1}{3}}$$

2 daraja ko‘rsatkichini \frac{2}{3} ga hisoblang va \frac{4}{9} ni qiymatni oling.

$$\frac{\frac{4}{9}+1-\frac{1}{9}}{2-\frac{1}{3}}$$

\frac{13}{9} olish uchun \frac{4}{9} va 1'ni qo'shing.

$$\frac{\frac{13}{9}-\frac{1}{9}}{2-\frac{1}{3}}$$

\frac{4}{3} olish uchun \frac{13}{9} dan \frac{1}{9} ni ayirish.

$$\frac{\frac{4}{3}}{2-\frac{1}{3}}$$

\frac{5}{3} olish uchun 2 dan \frac{1}{3} ni ayirish.

$$\frac{\frac{4}{3}}{\frac{5}{3}}$$

\frac{4}{3} ni \frac{5}{3} ga bo'lish \frac{4}{3} ga k'paytirish \frac{5}{3} ga qaytarish.

$$\frac{4}{3}\times \frac{3}{5}$$

\frac{4}{5} hosil qilish uchun \frac{4}{3} va \frac{3}{5} ni ko'paytirish.

$$\frac{4}{5}$$

Omil

$$\frac{2 ^ {2}}{5} = 0,8$$
