Yechim qadamlari

\frac{5^{2}-6}{3} ni \frac{1\times 3+5}{3} ga bo'lish \frac{5^{2}-6}{3} ga k'paytirish \frac{1\times 3+5}{3} ga qaytarish.

$$\frac{\left(5^{2}-6\right)\times 3}{3\left(1\times 3+5\right)}$$

Surat va maxrajdagi ikkala 3 ni qisqartiring.

$$\frac{5^{2}-6}{3+5}$$

2 daraja ko‘rsatkichini 5 ga hisoblang va 25 ni qiymatni oling.

$$\frac{25-6}{3+5}$$

19 olish uchun 25 dan 6 ni ayirish.

$$\frac{19}{3+5}$$

8 olish uchun 3 va 5'ni qo'shing.

$$\frac{19}{8}$$

Omil

$$\frac{19}{2 ^ {3}} = 2\frac{3}{8} = 2,375$$
