y=sqrt{9^2}+b_2^2 eching

$$y = \sqrt { 9 ^ { 2 } } + b _ { 2 } ^ { 2 }$$

y uchun yechish

$$y=b_{2}^{2}+9$$

Yechim qadamlari

2 daraja ko‘rsatkichini 9 ga hisoblang va 81 ni qiymatni oling.

$$y=\sqrt{81}+b_{2}^{2}$$

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

$$y=9+b_{2}^{2}$$

b_2 uchun yechish (complex solution)

$$b_{2}=-\sqrt{y-9}$$

$$b_{2}=\sqrt{y-9}$$

b_2 uchun yechish

$$b_{2}=\sqrt{y-9}$$

$$b_{2}=-\sqrt{y-9}\text{, }y\geq 9$$
