Hello!
\n" ); document.write( "You can use the following rule of logarithms:\r
\n" ); document.write( "\n" ); document.write( "\"log%28x%2Fy%29=log%28x%29-log%28y%29\"\r
\n" ); document.write( "\n" ); document.write( "So your equation becomes:\r
\n" ); document.write( "\n" ); document.write( "\"160+=+20log+%284%2Fm%29\"
\n" ); document.write( "Divide by 20
\n" ); document.write( "\"+8+=log%284%2Fm%29\"
\n" ); document.write( "Apply the log rule
\n" ); document.write( "\"+8+=+log%284%29+-+log%28m%29\"
\n" ); document.write( "\"log%28m%29+=+log%284%29-8\"
\n" ); document.write( "\"+m+=+10%5E%28log%284%29-8%29\"\r
\n" ); document.write( "
