Yechim qadamlari

2 daraja ko‘rsatkichini -\sqrt{5} ga hisoblang va \left(\sqrt{5}\right)^{2} ni qiymatni oling.

$$1\left(\sqrt{5}\right)^{2}-\sqrt{16}+\sqrt{\left(-2\right)^{2}}$$

16 ning kvadrat ildizini hisoblab, 4 natijaga ega bo‘ling.

$$1\left(\sqrt{5}\right)^{2}-4+\sqrt{\left(-2\right)^{2}}$$

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

$$1\left(\sqrt{5}\right)^{2}-4+\sqrt{4}$$

4 ning kvadrat ildizini hisoblab, 2 natijaga ega bo‘ling.

$$1\left(\sqrt{5}\right)^{2}-4+2$$

-2 olish uchun -4 va 2'ni qo'shing.

$$1\left(\sqrt{5}\right)^{2}-2$$

\sqrt{5} kvadrati – 5.

$$1\times 5-2$$

5 hosil qilish uchun 1 va 5 ni ko'paytirish.

$$5-2$$

3 olish uchun 5 dan 2 ni ayirish.
