Yechim qadamlari

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

$$\left(3\sqrt{2}\right)^{2}-4^{2}$$

\left(3\sqrt{2}\right)^{2} ni kengaytirish.

$$3^{2}\left(\sqrt{2}\right)^{2}-4^{2}$$

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

$$9\left(\sqrt{2}\right)^{2}-4^{2}$$

\sqrt{2} kvadrati – 2.

$$9\times 2-4^{2}$$

18 hosil qilish uchun 9 va 2 ni ko'paytirish.

$$18-4^{2}$$

2 daraja ko‘rsatkichini 4 ga hisoblang va 16 ni qiymatni oling.

$$18-16$$

2 olish uchun 18 dan 16 ni ayirish.
