Yechim qadamlari

0,81 olish uchun 1 dan 0,19 ni ayirish.

$$\frac{\sqrt{0,81}+0,3^{2}-\frac{6}{25}}{-3}$$

0,81 ning kvadrat ildizini hisoblab, 0,9 natijaga ega bo‘ling.

$$\frac{0,9+0,3^{2}-\frac{6}{25}}{-3}$$

2 daraja ko‘rsatkichini 0,3 ga hisoblang va 0,09 ni qiymatni oling.

$$\frac{0,9+0,09-\frac{6}{25}}{-3}$$

0,99 olish uchun 0,9 va 0,09'ni qo'shing.

$$\frac{0,99-\frac{6}{25}}{-3}$$

0,99 o‘nlik raqamni uning \frac{99}{100} kasrga o‘giring.

$$\frac{\frac{99}{100}-\frac{6}{25}}{-3}$$

100 va 25 ning eng kichik umumiy karralisi 100 ga teng. \frac{99}{100} va \frac{6}{25} ni 100 maxraj bilan kasrlarga aylantirib oling.

$$\frac{\frac{99}{100}-\frac{24}{100}}{-3}$$

\frac{99}{100} va \frac{24}{100} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{\frac{99-24}{100}}{-3}$$

75 olish uchun 99 dan 24 ni ayirish.

$$\frac{\frac{75}{100}}{-3}$$

\frac{75}{100} ulushini 25 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{\frac{3}{4}}{-3}$$

\frac{\frac{3}{4}}{-3} ni yagona kasrga aylantiring.

$$\frac{3}{4\left(-3\right)}$$

-12 hosil qilish uchun 4 va -3 ni ko'paytirish.

$$\frac{3}{-12}$$

\frac{3}{-12} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$-\frac{1}{4}$$
