left(4-3right)+left(1+2right)^2/6+left(7-5right) eching

$$\frac{ \left( 4-3 \right) + { \left( 1+2 \right) }^{ 2 } }{ 6+ \left( 7-5 \right) }$$

Baholash

$$\frac{5}{4}=1,25$$

Yechim qadamlari

1 olish uchun 4 dan 3 ni ayirish.

$$\frac{1+\left(1+2\right)^{2}}{6+7-5}$$

3 olish uchun 1 va 2'ni qo'shing.

$$\frac{1+3^{2}}{6+7-5}$$

2 daraja ko‘rsatkichini 3 ga hisoblang va 9 ni qiymatni oling.

$$\frac{1+9}{6+7-5}$$

10 olish uchun 1 va 9'ni qo'shing.

$$\frac{10}{6+7-5}$$

13 olish uchun 6 va 7'ni qo'shing.

$$\frac{10}{13-5}$$

8 olish uchun 13 dan 5 ni ayirish.

$$\frac{10}{8}$$

\frac{10}{8} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

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

Omil

$$\frac{5}{2 ^ {2}} = 1\frac{1}{4} = 1,25$$
