Yechim qadamlari

\left(-2\sqrt{5}\right)^{2} ni kengaytirish.

$$2\left(-2\right)^{2}\left(\sqrt{5}\right)^{2}+\sqrt{\left(-3\right)^{2}}$$

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

$$2\times 4\left(\sqrt{5}\right)^{2}+\sqrt{\left(-3\right)^{2}}$$

\sqrt{5} kvadrati – 5.

$$2\times 4\times 5+\sqrt{\left(-3\right)^{2}}$$

20 hosil qilish uchun 4 va 5 ni ko'paytirish.

$$2\times 20+\sqrt{\left(-3\right)^{2}}$$

40 hosil qilish uchun 2 va 20 ni ko'paytirish.

$$40+\sqrt{\left(-3\right)^{2}}$$

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

$$40+\sqrt{9}$$

9 ning kvadrat ildizini hisoblab, 3 natijaga ega bo‘ling.

$$40+3$$

43 olish uchun 40 va 3'ni qo'shing.
