Qisqa yechim qadamlari

Ifodalarni qo‘shish yoki ayirish uchun ularni yoyib, maxrajlarini bir xil qiling. 2 ni \frac{3}{3} marotabaga ko'paytirish.

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

-\frac{\sqrt{3}}{3} va \frac{2\times 3}{3} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

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

-\sqrt{3}-2\times 3 ichidagi ko‘paytirishlarni bajaring.

$$\frac{-\sqrt{3}-6}{3}$$

Omil

$$\frac{-\sqrt{3} - 6}{3} = -2,5773502691896257$$
