1. \(\log x = 9\\ \Leftrightarrow x = 10^{9} \\ \Leftrightarrow x =1000000000\)
2. \(\log x = 8\\ \Leftrightarrow x = 10^{8} \\ \Leftrightarrow x =100000000\)
3. \(\log x = 4\\ \Leftrightarrow x = 10^{4} \\ \Leftrightarrow x =10000\)
4. \(\log x = -8\\ \Leftrightarrow x = \log 10^{-8} \\ \Leftrightarrow x = \frac{1}{10^{8}}\)
5. \(\log x = 1\\ \Leftrightarrow x = 10^{1} \\ \Leftrightarrow x =10\)
6. \(\log x = \frac{3}{10}\\ \Leftrightarrow x =\log 10^{\frac{3}{10}}\\ \Leftrightarrow x =\sqrt[10]{ 10^{3} }\)
7. \(\log x = 7\\ \Leftrightarrow x = 10^{7} \\ \Leftrightarrow x =10000000\)
8. \(\log x = 3\\ \Leftrightarrow x = 10^{3} \\ \Leftrightarrow x =1000\)
9. \(\log x = \frac{3}{5}\\ \Leftrightarrow x =\log 10^{\frac{3}{5}}\\ \Leftrightarrow x =\sqrt[5]{ 10^{3} }\)
10. \(\log x = 6\\ \Leftrightarrow x = 10^{6} \\ \Leftrightarrow x =1000000\)
11. \(\log x = 2\\ \Leftrightarrow x = 10^{2} \\ \Leftrightarrow x =100\)
12. \(\log x = \frac{-1}{12}\\ \Leftrightarrow x =\log 10^{\frac{-1}{12}}\\ \Leftrightarrow x =\sqrt[12]{ \frac{1}{10^{1}} }\)
