Yechim qadamlari

21^{2} ni 21\times 21 sifatida qaytadan yozish. Surat va maxrajdagi ikkala 21 ni qisqartiring.

$$27\times 21+\frac{1}{21}+21=462$$

567 hosil qilish uchun 27 va 21 ni ko'paytirish.

$$567+\frac{1}{21}+21=462$$

567 ni \frac{11907}{21} kasrga o‘giring.

$$\frac{11907}{21}+\frac{1}{21}+21=462$$

\frac{11907}{21} va \frac{1}{21} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{11907+1}{21}+21=462$$

11908 olish uchun 11907 va 1'ni qo'shing.

$$\frac{11908}{21}+21=462$$

21 ni \frac{441}{21} kasrga o‘giring.

$$\frac{11908}{21}+\frac{441}{21}=462$$

\frac{11908}{21} va \frac{441}{21} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{11908+441}{21}=462$$

12349 olish uchun 11908 va 441'ni qo'shing.

$$\frac{12349}{21}=462$$

462 ni \frac{9702}{21} kasrga o‘giring.

$$\frac{12349}{21}=\frac{9702}{21}$$

\frac{12349}{21} va \frac{9702}{21} ni taqqoslang.
