Yechim qadamlari

Ko‘paytirish qoida yordamida turli kvadratlarga aylantirilishi mumkin: \left(a-b\right)\left(a+b\right)=a^{2}-b^{2}.

$$1^{2}-\left(8\sqrt{2}\right)^{2}$$

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

$$1-\left(8\sqrt{2}\right)^{2}$$

\left(8\sqrt{2}\right)^{2} ni kengaytirish.

$$1-8^{2}\left(\sqrt{2}\right)^{2}$$

2 daraja ko‘rsatkichini 8 ga hisoblang va 64 ni qiymatni oling.

$$1-64\left(\sqrt{2}\right)^{2}$$

\sqrt{2} kvadrati – 2.

$$1-64\times 2$$

128 hosil qilish uchun 64 va 2 ni ko'paytirish.

$$1-128$$

-127 olish uchun 1 dan 128 ni ayirish.
