Yechim qadamlari

49 ning kvadrat ildizini hisoblab, 7 natijaga ega bo‘ling.

$$7+\sqrt[3]{-8}-\left(-4\right)^{3}$$

\sqrt[3]{-8} ni hisoblab, -2 natijasiga ega bo‘ling.

$$7-2-\left(-4\right)^{3}$$

5 olish uchun 7 dan 2 ni ayirish.

$$5-\left(-4\right)^{3}$$

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

$$5-\left(-64\right)$$

-64 ning teskarisi 64 ga teng.

$$5+64$$

69 olish uchun 5 va 64'ni qo'shing.
