Yechim qadamlari

\frac{30}{2} hosil qilish uchun \frac{1}{2} va 30 ni ko'paytirish.

$$\frac{30}{2}\left(253^{2}-1^{2}\right)$$

15 ni olish uchun 30 ni 2 ga bo‘ling.

$$15\left(253^{2}-1^{2}\right)$$

2 daraja ko‘rsatkichini 253 ga hisoblang va 64009 ni qiymatni oling.

$$15\left(64009-1^{2}\right)$$

2 daraja ko‘rsatkichini 1 ga hisoblang va 1 ni qiymatni oling.

$$15\left(64009-1\right)$$

64008 olish uchun 64009 dan 1 ni ayirish.

$$15\times 64008$$

960120 hosil qilish uchun 15 va 64008 ni ko'paytirish.

$$960120$$
