-2^3+1/3*(201+3)^0-(-1/3)^-2 eching

$$- 2 ^ { 3 } + \frac { 1 } { 3 } \times ( 201 + 3 ) ^ { 0 } - ( - \frac { 1 } { 3 } ) ^ { - 2 }$$

Baholash

$$-\frac{50}{3}\approx -16,666666667$$

Yechim qadamlari

3 daraja ko‘rsatkichini 2 ga hisoblang va 8 ni qiymatni oling.

$$-8+\frac{1}{3}\left(201+3\right)^{0}-\left(-\frac{1}{3}\right)^{-2}$$

204 olish uchun 201 va 3'ni qo'shing.

$$-8+\frac{1}{3}\times 204^{0}-\left(-\frac{1}{3}\right)^{-2}$$

0 daraja ko‘rsatkichini 204 ga hisoblang va 1 ni qiymatni oling.

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

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

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

-\frac{23}{3} olish uchun -8 va \frac{1}{3}'ni qo'shing.

$$-\frac{23}{3}-\left(-\frac{1}{3}\right)^{-2}$$

-2 daraja ko‘rsatkichini -\frac{1}{3} ga hisoblang va 9 ni qiymatni oling.

$$-\frac{23}{3}-9$$

-\frac{50}{3} olish uchun -\frac{23}{3} dan 9 ni ayirish.

$$-\frac{50}{3}$$

Omil

$$-\frac{50}{3} = -16\frac{2}{3} = -16,666666666666668$$
