Yechim qadamlari

2 daraja ko‘rsatkichini 4 ga hisoblang va 16 ni qiymatni oling.

$$-4\sqrt{16-\frac{4\times 2\left(-16\right)}{2}\times 2}$$

2 va 2 ni qisqartiring.

$$-4\sqrt{16-4\left(-16\right)\times 2}$$

-64 hosil qilish uchun 4 va -16 ni ko'paytirish.

$$-4\sqrt{16-\left(-64\times 2\right)}$$

-128 hosil qilish uchun -64 va 2 ni ko'paytirish.

$$-4\sqrt{16-\left(-128\right)}$$

-128 ning teskarisi 128 ga teng.

$$-4\sqrt{16+128}$$

144 olish uchun 16 va 128'ni qo'shing.

$$-4\sqrt{144}$$

144 ning kvadrat ildizini hisoblab, 12 natijaga ega bo‘ling.

$$-4\times 12$$

-48 hosil qilish uchun -4 va 12 ni ko'paytirish.
