sqrt{-2^2}=left|-1right|+1/9*-3^2+sqrt[3]{-8} eching

$$\sqrt{ { -2 }^{ 2 } } = \left| -1 \right| + \frac{ 1 }{ 9 } \times { -3 }^{ 2 } + \sqrt[ 3 ]{ -8 }$$

Yechim qadamlari

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

$$\sqrt{4}=|-1|+\frac{1}{9}\left(-3\right)^{2}+\sqrt[3]{-8}$$

4 ning kvadrat ildizini hisoblab, 2 natijaga ega bo‘ling.

$$2=|-1|+\frac{1}{9}\left(-3\right)^{2}+\sqrt[3]{-8}$$

a haqiqiy sonining mutloq qiymati qachon a\geq 0 bo‘lganda, a yoki qachon a<0 bo‘lganda -a. -1 ning mutloq qiymati 1 ga teng.

$$2=1+\frac{1}{9}\left(-3\right)^{2}+\sqrt[3]{-8}$$

2 daraja ko‘rsatkichini -3 ga hisoblang va 9 ni qiymatni oling.

$$2=1+\frac{1}{9}\times 9+\sqrt[3]{-8}$$

1 hosil qilish uchun \frac{1}{9} va 9 ni ko'paytirish.

$$2=1+1+\sqrt[3]{-8}$$

2 olish uchun 1 va 1'ni qo'shing.

$$2=2+\sqrt[3]{-8}$$

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

$$2=2-2$$

0 olish uchun 2 dan 2 ni ayirish.

$$2=0$$

2 va 0 ni taqqoslang.
