Which property or axoim is shown below \[ \begin{array}{l}5+0=5 \\ \text { additive identity } \\ \text { additive inverse } \\ \text { associative axiom } \\ \text { commuative axiom }\end{array} \]

Simplify \( \sqrt{6}(\sqrt{18}+\sqrt{8}) \)

Hisoblang: \( \sqrt{66^{2}-44^{2}-22^{2}} \) \( \begin{array}{llll}\text { A) } 22 & \text { B) } 44 & \text { C) } 0 & \text { D) } 33\end{array} \)

2. The value of \( \frac{(0.1)^{2}-(0.01)^{2}}{0.0001}+1 \) is

b. \( \quad \) Simplify \( (\sqrt{5})^{-2} \times 75^{1 / 2} \times 12^{-1 / 2} \)

e) \( \sqrt[2]{\left(\frac{49}{9}\right)^{11} \cdot\left(\frac{49}{9}\right)^{-4}:\left(\frac{98}{18}\right)^{6}: \frac{196}{36}+[3-(0, \hat{6}-1)]^{2}}= \)
