Yechim qadamlari

1 ni olish uchun 3 ni 3 ga bo‘ling.

$$-\left(\frac{3}{4}-2\right)+1+\left(-1\right)^{3}+2\times 2-3$$

2 ni \frac{8}{4} kasrga o‘giring.

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

\frac{3}{4} va \frac{8}{4} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

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

-5 olish uchun 3 dan 8 ni ayirish.

$$-\left(-\frac{5}{4}\right)+1+\left(-1\right)^{3}+2\times 2-3$$

-\frac{5}{4} ning teskarisi \frac{5}{4} ga teng.

$$\frac{5}{4}+1+\left(-1\right)^{3}+2\times 2-3$$

1 ni \frac{4}{4} kasrga o‘giring.

$$\frac{5}{4}+\frac{4}{4}+\left(-1\right)^{3}+2\times 2-3$$

\frac{5}{4} va \frac{4}{4} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{5+4}{4}+\left(-1\right)^{3}+2\times 2-3$$

9 olish uchun 5 va 4'ni qo'shing.

$$\frac{9}{4}+\left(-1\right)^{3}+2\times 2-3$$

3 daraja ko‘rsatkichini -1 ga hisoblang va -1 ni qiymatni oling.

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

1 ni \frac{4}{4} kasrga o‘giring.

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

\frac{9}{4} va \frac{4}{4} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

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

5 olish uchun 9 dan 4 ni ayirish.

$$\frac{5}{4}+2\times 2-3$$

4 hosil qilish uchun 2 va 2 ni ko'paytirish.

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

4 ni \frac{16}{4} kasrga o‘giring.

$$\frac{5}{4}+\frac{16}{4}-3$$

\frac{5}{4} va \frac{16}{4} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{5+16}{4}-3$$

21 olish uchun 5 va 16'ni qo'shing.

$$\frac{21}{4}-3$$

3 ni \frac{12}{4} kasrga o‘giring.

$$\frac{21}{4}-\frac{12}{4}$$

\frac{21}{4} va \frac{12}{4} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{21-12}{4}$$

9 olish uchun 21 dan 12 ni ayirish.

$$\frac{9}{4}$$

Omil

$$\frac{3 ^ {2}}{2 ^ {2}} = 2\frac{1}{4} = 2,25$$
