Verbetersleutel

  1. \(\log x = \frac{1}{3}\\ \Leftrightarrow x =\log 10^{\frac{1}{3}}\\ \Leftrightarrow x =\sqrt[3]{ 10 }\)
  2. \(\log x = \frac{-8}{3}\\ \Leftrightarrow x =\log 10^{\frac{-8}{3}}\\ \Leftrightarrow x =\sqrt[3]{ \frac{1}{10^{8}} }\)
  3. \(\log x = -3\\ \Leftrightarrow x = 10^{-3} \\ \Leftrightarrow x =0{,}001\)
  4. \(\log x = -4\\ \Leftrightarrow x = \log 10^{-4} \\ \Leftrightarrow x = \frac{1}{10^{4}}\)
  5. \(\log x = 7\\ \Leftrightarrow x = 10^{7} \\ \Leftrightarrow x =10000000\)
  6. \(\log x = -5\\ \Leftrightarrow x = \log 10^{-5} \\ \Leftrightarrow x = \frac{1}{10^{5}}\)
  7. \(\log x = -7\\ \Leftrightarrow x = \log 10^{-7} \\ \Leftrightarrow x = \frac{1}{10^{7}}\)
  8. \(\log x = \frac{7}{2}\\ \Leftrightarrow x =\log 10^{\frac{7}{2}}\\ \Leftrightarrow x = \sqrt{ 10^{7} } \)
  9. \(\log x = 4\\ \Leftrightarrow x = 10^{4} \\ \Leftrightarrow x =10000\)
  10. \(\log x = \frac{9}{2}\\ \Leftrightarrow x =\log 10^{\frac{9}{2}}\\ \Leftrightarrow x = \sqrt{ 10^{9} } \)
  11. \(\log x = 6\\ \Leftrightarrow x = 10^{6} \\ \Leftrightarrow x =1000000\)
  12. \(\log x = -2\\ \Leftrightarrow x = 10^{-2} \\ \Leftrightarrow x =0{,}01\)
