4^3(-12+2^2)/(2*3)^2+(-5*2*3)+2 eching

$$\frac { 4 ^ { 3 } ( - 12 + 2 ^ { 2 } ) } { ( 2 \times 3 ) ^ { 2 } + ( - 5 \times 2 \times 3 ) } + 2$$

$$-\frac{250}{3}\approx -83,333333333$$

Yechim qadamlari

3 daraja ko‘rsatkichini 4 ga hisoblang va 64 ni qiymatni oling.

$$\frac{64\left(-12+2^{2}\right)}{\left(2\times 3\right)^{2}-5\times 2\times 3}+2$$

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

$$\frac{64\left(-12+4\right)}{\left(2\times 3\right)^{2}-5\times 2\times 3}+2$$

-8 olish uchun -12 va 4'ni qo'shing.

$$\frac{64\left(-8\right)}{\left(2\times 3\right)^{2}-5\times 2\times 3}+2$$

-512 hosil qilish uchun 64 va -8 ni ko'paytirish.

$$\frac{-512}{\left(2\times 3\right)^{2}-5\times 2\times 3}+2$$

6 hosil qilish uchun 2 va 3 ni ko'paytirish.

$$\frac{-512}{6^{2}-5\times 2\times 3}+2$$

2 daraja ko‘rsatkichini 6 ga hisoblang va 36 ni qiymatni oling.

$$\frac{-512}{36-5\times 2\times 3}+2$$

-10 hosil qilish uchun -5 va 2 ni ko'paytirish.

$$\frac{-512}{36-10\times 3}+2$$

-30 hosil qilish uchun -10 va 3 ni ko'paytirish.

$$\frac{-512}{36-30}+2$$

6 olish uchun 36 dan 30 ni ayirish.

$$\frac{-512}{6}+2$$

\frac{-512}{6} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$-\frac{256}{3}+2$$

-\frac{250}{3} olish uchun -\frac{256}{3} va 2'ni qo'shing.

$$-\frac{250}{3}$$

Omil

$$-\frac{250}{3} = -83\frac{1}{3} = -83,33333333333333$$
