(-1)^4-(1-05)*1/3*[2-(-2)^2] eching

$$( - 1 ) ^ { 4 } - ( 1 - 05 ) \times \frac { 1 } { 3 } \times [ 2 - ( - 2 ) ^ { 2 } ]$$

Baholash

$$\frac{5}{3}\approx 1,666666667$$

Yechim qadamlari

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

$$1-\left(1-0\times 5\right)\times \frac{1}{3}\left(2-\left(-2\right)^{2}\right)$$

0 hosil qilish uchun 0 va 5 ni ko'paytirish.

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

1 olish uchun 1 dan 0 ni ayirish.

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

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

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

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

$$1-\frac{1}{3}\left(2-4\right)$$

-2 olish uchun 2 dan 4 ni ayirish.

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

\frac{-2}{3} hosil qilish uchun \frac{1}{3} va -2 ni ko'paytirish.

$$1-\frac{-2}{3}$$

\frac{-2}{3} kasri manfiy belgini olib tashlash bilan -\frac{2}{3} sifatida qayta yozilishi mumkin.

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

-\frac{2}{3} ning teskarisi \frac{2}{3} ga teng.

$$1+\frac{2}{3}$$

1 ni \frac{3}{3} kasrga o‘giring.

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

\frac{3}{3} va \frac{2}{3} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

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

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

$$\frac{5}{3}$$

Omil

$$\frac{5}{3} = 1\frac{2}{3} = 1,6666666666666667$$
