Yechim qadamlari

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

$$7^{2}-\left(4\sqrt{3}\right)^{2}$$

2 daraja ko‘rsatkichini 7 ga hisoblang va 49 ni qiymatni oling.

$$49-\left(4\sqrt{3}\right)^{2}$$

\left(4\sqrt{3}\right)^{2} ni kengaytirish.

$$49-4^{2}\left(\sqrt{3}\right)^{2}$$

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

$$49-16\left(\sqrt{3}\right)^{2}$$

\sqrt{3} kvadrati – 3.

$$49-16\times 3$$

48 hosil qilish uchun 16 va 3 ni ko'paytirish.

$$49-48$$

1 olish uchun 49 dan 48 ni ayirish.
