Yechim qadamlari

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

$$\frac{-2+\sqrt{16-4}}{2}$$

12 olish uchun 16 dan 4 ni ayirish.

$$\frac{-2+\sqrt{12}}{2}$$

Faktor: 12=2^{2}\times 3. \sqrt{2^{2}\times 3} koʻpaytmasining kvadrat ildizini \sqrt{2^{2}}\sqrt{3} kvadrat ildizlarining koʻpaytmasi sifatida qayta yozing. 2^{2} ning kvadrat ildizini chiqarish.

$$\frac{-2+2\sqrt{3}}{2}$$

-1+\sqrt{3} natijani olish uchun -2+2\sqrt{3} ning har bir ifodasini 2 ga bo‘ling.

$$-1+\sqrt{3}$$

Omil

$$\sqrt{3} - 1 = 0,732050808$$
