You can put this solution on YOUR website!
2x = 30
\n" ); document.write( "=> log(2x) = log(30)
\n" ); document.write( "=> log 2 + log x = log 30
\n" ); document.write( "=> log x = log 2 - log 30 = log (2/30) = log (1/15)
\n" ); document.write( "=> x = 1/15 = .067
\n" ); document.write( "Follow the same procedure as above to solve the rest of the problems. Shoot an email if you have difficulties.
