$$\frac { \frac { \sqrt { 2 } } { 2 } + 3 ^ { 2 } } { 21 }$$

Baholash

$$\frac{\sqrt{2}}{42}+\frac{3}{7}\approx 0,46224318$$

Qisqa yechim qadamlari

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

$$\frac{\frac{\sqrt{2}}{2}+9}{21}$$

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

$$\frac{\frac{\sqrt{2}}{2}+\frac{9\times 2}{2}}{21}$$

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

$$\frac{\frac{\sqrt{2}+9\times 2}{2}}{21}$$

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

$$\frac{\frac{\sqrt{2}+18}{2}}{21}$$

\frac{\frac{\sqrt{2}+18}{2}}{21} ni yagona kasrga aylantiring.

$$\frac{\sqrt{2}+18}{2\times 21}$$

42 hosil qilish uchun 2 va 21 ni ko'paytirish.

$$\frac{\sqrt{2}+18}{42}$$

Omil

$$\frac{\sqrt{2} + 18}{42} = 0,4622431800565023$$
