Baholash

$$\frac{\sqrt{2}}{2}+9\approx 9,707106781$$

Qisqa yechim qadamlari

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

$$\frac{\sqrt{2}}{2}+9$$

Ifodalarni qo‘shish yoki ayirish uchun ularni yoyib, maxrajlarini bir xil qiling. 9 ni \frac{2}{2} marotabaga ko'paytirish.

$$\frac{\sqrt{2}}{2}+\frac{9\times 2}{2}$$

\frac{\sqrt{2}}{2} va \frac{9\times 2}{2} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{\sqrt{2}+9\times 2}{2}$$

\sqrt{2}+9\times 2 ichidagi ko‘paytirishlarni bajaring.

$$\frac{\sqrt{2}+18}{2}$$

Omil

$$\frac{\sqrt{2} + 18}{2} = 9,707106781186548$$
