Yechim qadamlari

\frac{7}{4} olish uchun 2 dan \frac{1}{4} ni ayirish.

$$\left(\frac{7}{4}\left(3-\frac{1}{2}\right)\right)^{2}-\sqrt{9}$$

\frac{5}{2} olish uchun 3 dan \frac{1}{2} ni ayirish.

$$\left(\frac{7}{4}\times \frac{5}{2}\right)^{2}-\sqrt{9}$$

\frac{35}{8} hosil qilish uchun \frac{7}{4} va \frac{5}{2} ni ko'paytirish.

$$\left(\frac{35}{8}\right)^{2}-\sqrt{9}$$

2 daraja ko‘rsatkichini \frac{35}{8} ga hisoblang va \frac{1225}{64} ni qiymatni oling.

$$\frac{1225}{64}-\sqrt{9}$$

9 ning kvadrat ildizini hisoblab, 3 natijaga ega bo‘ling.

$$\frac{1225}{64}-3$$

\frac{1033}{64} olish uchun \frac{1225}{64} dan 3 ni ayirish.
