I'd be very, very grateful if you could solve the following for me:
\n" ); document.write( "5/[10^(2x)]=7
\n" ); document.write( "10^(2x)=5/7
\n" ); document.write( "take log of both sides
\n" ); document.write( "(2x)log10=log5-log7
\n" ); document.write( "2x=log5-log7
\n" ); document.write( "x=(log5-log7)/2≈-0.0731
\n" ); document.write( "
\n" );
