1. \(\log x = 4\\ \Leftrightarrow x = 10^{4} \\ \Leftrightarrow x =10000\)
2. \(\log x = 5\\ \Leftrightarrow x = 10^{5} \\ \Leftrightarrow x =100000\)
3. \(\log x = -3\\ \Leftrightarrow x = 10^{-3} \\ \Leftrightarrow x =0,001\)
4. \(\log x = -2\\ \Leftrightarrow x = 10^{-2} \\ \Leftrightarrow x =0,01\)
5. \(\log x = -7\\ \Leftrightarrow x = \log 10^{-7} \\ \Leftrightarrow x = \frac{1}{10^{7}}\)
6. \(\log x = \frac{-5}{1}\\ \Leftrightarrow x =\log 10^{\frac{-5}{1}}\\ \Leftrightarrow x =\frac{1}{10^{5}}\)
7. \(\log x = \frac{5}{3}\\ \Leftrightarrow x =\log 10^{\frac{5}{3}}\\ \Leftrightarrow x =\sqrt[3]{ 10^{5} }\)
8. \(\log x = \frac{-9}{8}\\ \Leftrightarrow x =\log 10^{\frac{-9}{8}}\\ \Leftrightarrow x =\sqrt[8]{ \frac{1}{10^{9}} }\)
9. \(\log x = 6\\ \Leftrightarrow x = 10^{6} \\ \Leftrightarrow x =1000000\)
10. \(\log x = -1\\ \Leftrightarrow x = \log 10^{-1} \\ \Leftrightarrow x = \frac{1}{10^{1}}\)
11. \(\log x = -8\\ \Leftrightarrow x = \log 10^{-8} \\ \Leftrightarrow x = \frac{1}{10^{8}}\)
12. \(\log x = \frac{3}{2}\\ \Leftrightarrow x =\log 10^{\frac{3}{2}}\\ \Leftrightarrow x = \sqrt{ 10^{3} } \)
