Verbetersleutel

1. \(\log x = -9\\ \Leftrightarrow x = \log 10^{-9} \\ \Leftrightarrow x = \frac{1}{10^{9}}\)
2. \(\log x = -6\\ \Leftrightarrow x = \log 10^{-6} \\ \Leftrightarrow x = \frac{1}{10^{6}}\)
3. \(\log x = 2\\ \Leftrightarrow x = 10^{2} \\ \Leftrightarrow x =100\)
4. \(\log x = \frac{-1}{3}\\ \Leftrightarrow x =\log 10^{\frac{-1}{3}}\\ \Leftrightarrow x =\sqrt[3]{ \frac{1}{10^{1}} }\)
5. \(\log x = 8\\ \Leftrightarrow x = 10^{8} \\ \Leftrightarrow x =100000000\)
6. \(\log x = 9\\ \Leftrightarrow x = 10^{9} \\ \Leftrightarrow x =1000000000\)
7. \(\log x = \frac{3}{1}\\ \Leftrightarrow x =\log 10^{\frac{3}{1}}\\ \Leftrightarrow x =10^{3}\)
8. \(\log x = -7\\ \Leftrightarrow x = \log 10^{-7} \\ \Leftrightarrow x = \frac{1}{10^{7}}\)
9. \(\log x = -4\\ \Leftrightarrow x = \log 10^{-4} \\ \Leftrightarrow x = \frac{1}{10^{4}}\)
10. \(\log x = 7\\ \Leftrightarrow x = 10^{7} \\ \Leftrightarrow x =10000000\)
11. \(\log x = -1\\ \Leftrightarrow x = 10^{-1} \\ \Leftrightarrow x =0{,}1\)
12. \(\log x = \frac{4}{1}\\ \Leftrightarrow x =\log 10^{\frac{4}{1}}\\ \Leftrightarrow x =10^{4}\)
