Yechim qadamlari

376 ni olish uchun 752 ni 2 ga bo‘ling.

$$376+\frac{\frac{7}{2}}{\sqrt{196}}$$

196 ning kvadrat ildizini hisoblab, 14 natijaga ega bo‘ling.

$$376+\frac{\frac{7}{2}}{14}$$

\frac{\frac{7}{2}}{14} ni yagona kasrga aylantiring.

$$376+\frac{7}{2\times 14}$$

28 hosil qilish uchun 2 va 14 ni ko'paytirish.

$$376+\frac{7}{28}$$

\frac{7}{28} ulushini 7 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$376+\frac{1}{4}$$

376 ni \frac{1504}{4} kasrga o‘giring.

$$\frac{1504}{4}+\frac{1}{4}$$

\frac{1504}{4} va \frac{1}{4} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{1504+1}{4}$$

1505 olish uchun 1504 va 1'ni qo'shing.

$$\frac{1505}{4}$$

Omil

$$\frac{5 \cdot 7 \cdot 43}{2 ^ {2}} = 376\frac{1}{4} = 376,25$$
