Yechim qadamlari

I^{2} hosil qilish uchun I va I ni ko'paytirish.

$$\left(-3^{2}\right)I^{2}\times 47^{2}-\frac{3^{4}}{9}$$

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

$$-9I^{2}\times 47^{2}-\frac{3^{4}}{9}$$

2 daraja ko‘rsatkichini 47 ga hisoblang va 2209 ni qiymatni oling.

$$-9I^{2}\times 2209-\frac{3^{4}}{9}$$

-19881 hosil qilish uchun -9 va 2209 ni ko'paytirish.

$$-19881I^{2}-\frac{3^{4}}{9}$$

4 daraja ko‘rsatkichini 3 ga hisoblang va 81 ni qiymatni oling.

$$-19881I^{2}-\frac{81}{9}$$

9 ni olish uchun 81 ni 9 ga bo‘ling.

$$-19881I^{2}-9$$
