2*(3/2)^2-2*1^2 eching

$$2 \times ( \frac { 3 } { 2 } ) ^ { 2 } - 2 \times 1 ^ { 2 }$$

Baholash

$$\frac{5}{2}=2,5$$

Yechim qadamlari

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

$$2\times \frac{9}{4}-2\times 1^{2}$$

2\times \frac{9}{4} ni yagona kasrga aylantiring.

$$\frac{2\times 9}{4}-2\times 1^{2}$$

18 hosil qilish uchun 2 va 9 ni ko'paytirish.

$$\frac{18}{4}-2\times 1^{2}$$

\frac{18}{4} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{9}{2}-2\times 1^{2}$$

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

$$\frac{9}{2}-2\times 1$$

2 hosil qilish uchun 2 va 1 ni ko'paytirish.

$$\frac{9}{2}-2$$

2 ni \frac{4}{2} kasrga o‘giring.

$$\frac{9}{2}-\frac{4}{2}$$

\frac{9}{2} va \frac{4}{2} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{9-4}{2}$$

5 olish uchun 9 dan 4 ni ayirish.

$$\frac{5}{2}$$

Omil

$$\frac{5}{2} = 2\frac{1}{2} = 2,5$$
