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

Resolver: a) \( \frac{5}{8} \cdot\left(\frac{1}{4}\right)^{-1}+\frac{9}{5} \cdot \sqrt{\frac{27}{9} \cdot 3}-\frac{7}{10}+0,8= \)

Evaluate each expression. \[ \begin{array}{l}\text { (a) } \log _{5} \frac{1}{5}=\square \\ \text { (b) } \log _{2} 32=\square\end{array} \]

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

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

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