(2-1/4)*(3-1/2)]-sqrt{1/9} eching

$$( 2 - \frac { 1 } { 4 } ) \cdot ( 3 - \frac { 1 } { 2 } ) ] - \sqrt { \frac { 1 } { 9 } }$$

Baholash

$$\frac{35}{8}=4,375$$

Yechim qadamlari

2 ni \frac{8}{4} kasrga o‘giring.

$$\left(\frac{8}{4}-\frac{1}{4}\right)\left(3-\frac{1}{2}\right)$$

\frac{8}{4} va \frac{1}{4} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{8-1}{4}\left(3-\frac{1}{2}\right)$$

7 olish uchun 8 dan 1 ni ayirish.

$$\frac{7}{4}\left(3-\frac{1}{2}\right)$$

3 ni \frac{6}{2} kasrga o‘giring.

$$\frac{7}{4}\left(\frac{6}{2}-\frac{1}{2}\right)$$

\frac{6}{2} va \frac{1}{2} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{7}{4}\times \frac{6-1}{2}$$

5 olish uchun 6 dan 1 ni ayirish.

$$\frac{7}{4}\times \frac{5}{2}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{7}{4} ni \frac{5}{2} ga ko‘paytiring.

$$\frac{7\times 5}{4\times 2}$$

\frac{7\times 5}{4\times 2} kasridagi ko‘paytirishlarni bajaring.

$$\frac{35}{8}$$

Omil

$$\frac{5 \cdot 7}{2 ^ {3}} = 4\frac{3}{8} = 4,375$$
