Yechim qadamlari

3 daraja ko‘rsatkichini -7 ga hisoblang va -343 ni qiymatni oling.

$$-343+\left(-2\right)^{3}-\left(-21+35-\sqrt[3]{125}\left(-8\right)\right)$$

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

$$-343-8-\left(-21+35-\sqrt[3]{125}\left(-8\right)\right)$$

-351 olish uchun -343 dan 8 ni ayirish.

$$-351-\left(-21+35-\sqrt[3]{125}\left(-8\right)\right)$$

14 olish uchun -21 va 35'ni qo'shing.

$$-351-\left(14-\sqrt[3]{125}\left(-8\right)\right)$$

\sqrt[3]{125} ni hisoblab, 5 natijasiga ega bo‘ling.

$$-351-\left(14-5\left(-8\right)\right)$$

-40 hosil qilish uchun 5 va -8 ni ko'paytirish.

$$-351-\left(14-\left(-40\right)\right)$$

-40 ning teskarisi 40 ga teng.

$$-351-\left(14+40\right)$$

54 olish uchun 14 va 40'ni qo'shing.

$$-351-54$$

-405 olish uchun -351 dan 54 ni ayirish.

$$-405$$
