1. \(\log x = -9\\ \Leftrightarrow x = \log 10^{-9} \\ \Leftrightarrow x = \frac{1}{10^{9}}\)
2. \(\log x = -1\\ \Leftrightarrow x = \log 10^{-1} \\ \Leftrightarrow x = \frac{1}{10^{1}}\)
3. \(\log x = 2\\ \Leftrightarrow x = 10^{2} \\ \Leftrightarrow x =100\)
4. \(\log x = -2\\ \Leftrightarrow x = \log 10^{-2} \\ \Leftrightarrow x = \frac{1}{10^{2}}\)
5. \(\log x = \frac{-1}{2}\\ \Leftrightarrow x =\log 10^{\frac{-1}{2}}\\ \Leftrightarrow x = \sqrt{ \frac{1}{10^{1}} } \)
6. \(\log x = -5\\ \Leftrightarrow x = \log 10^{-5} \\ \Leftrightarrow x = \frac{1}{10^{5}}\)
7. \(\log x = -6\\ \Leftrightarrow x = \log 10^{-6} \\ \Leftrightarrow x = \frac{1}{10^{6}}\)
8. \(\log x = \frac{-2}{5}\\ \Leftrightarrow x =\log 10^{\frac{-2}{5}}\\ \Leftrightarrow x =\sqrt[5]{ \frac{1}{10^{2}} }\)
9. \(\log x = \frac{-3}{11}\\ \Leftrightarrow x =\log 10^{\frac{-3}{11}}\\ \Leftrightarrow x =\sqrt[11]{ \frac{1}{10^{3}} }\)
10. \(\log x = 9\\ \Leftrightarrow x = 10^{9} \\ \Leftrightarrow x =1000000000\)
11. \(\log x = \frac{-1}{7}\\ \Leftrightarrow x =\log 10^{\frac{-1}{7}}\\ \Leftrightarrow x =\sqrt[7]{ \frac{1}{10^{1}} }\)
