Yechim qadamlari

-2 olish uchun -2 dan 0 ni ayirish.

$$\left(-2\right)^{2}\times \frac{4}{9}+\left(0-0\right)^{2}\times \frac{3}{9}+\left(1-0\right)^{2}\times \frac{2}{9}$$

2 daraja ko‘rsatkichini -2 ga hisoblang va 4 ni qiymatni oling.

$$4\times \frac{4}{9}+\left(0-0\right)^{2}\times \frac{3}{9}+\left(1-0\right)^{2}\times \frac{2}{9}$$

\frac{16}{9} hosil qilish uchun 4 va \frac{4}{9} ni ko'paytirish.

$$\frac{16}{9}+\left(0-0\right)^{2}\times \frac{3}{9}+\left(1-0\right)^{2}\times \frac{2}{9}$$

O‘zidan 0 ayirilsa 0 qoladi.

$$\frac{16}{9}+0^{2}\times \frac{3}{9}+\left(1-0\right)^{2}\times \frac{2}{9}$$

2 daraja ko‘rsatkichini 0 ga hisoblang va 0 ni qiymatni oling.

$$\frac{16}{9}+0\times \frac{3}{9}+\left(1-0\right)^{2}\times \frac{2}{9}$$

\frac{3}{9} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{16}{9}+0\times \frac{1}{3}+\left(1-0\right)^{2}\times \frac{2}{9}$$

0 hosil qilish uchun 0 va \frac{1}{3} ni ko'paytirish.

$$\frac{16}{9}+0+\left(1-0\right)^{2}\times \frac{2}{9}$$

\frac{16}{9} olish uchun \frac{16}{9} va 0'ni qo'shing.

$$\frac{16}{9}+\left(1-0\right)^{2}\times \frac{2}{9}$$

1 olish uchun 1 dan 0 ni ayirish.

$$\frac{16}{9}+1^{2}\times \frac{2}{9}$$

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

$$\frac{16}{9}+1\times \frac{2}{9}$$

\frac{2}{9} hosil qilish uchun 1 va \frac{2}{9} ni ko'paytirish.

$$\frac{16}{9}+\frac{2}{9}$$

2 olish uchun \frac{16}{9} va \frac{2}{9}'ni qo'shing.
