-(-2)+sqrt{(-2)^2}=4*2(-1) eching

$$- ( - 2 ) + \sqrt { ( - 2 ) ^ { 2 } } = 4 \times 2 ( - 1 )$$

Tasdiqlamoq

Yechim qadamlari

-2 ning teskarisi 2 ga teng.

$$2+\sqrt{\left(-2\right)^{2}}=4\times 2\left(-1\right)$$

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

$$2+\sqrt{4}=4\times 2\left(-1\right)$$

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

$$2+2=4\times 2\left(-1\right)$$

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

$$4=4\times 2\left(-1\right)$$

8 hosil qilish uchun 4 va 2 ni ko'paytirish.

$$4=8\left(-1\right)$$

-8 hosil qilish uchun 8 va -1 ni ko'paytirish.

$$4=-8$$

4 va -8 ni taqqoslang.
