Use a variable.
\n" ); document.write( "\"5%5Ex=19\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"log%2810%2C%285%5Ex%29%29=log%2810%2C19%29\"
\n" ); document.write( "\"x%2Alog%2810%2C5%29=log%2810%2C19%29\"
\n" ); document.write( "\"x=log%2810%2C19%29%2Flog%2810%2C5%29\"
\n" ); document.write( "\"highlight%28x=1.2788%2F0.6990%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "That was not according to the instructions you listed. Your instructions would be like,
\n" ); document.write( "\"log%285%2C19%29=x\" and then use the change of base formula.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "-
\n" ); document.write( "CHANGE OF BASE FORMULA
\n" ); document.write( "Convert logarithm in base b into logarithm in base c
\n" ); document.write( "\"log%28b%2Cp%29=log%28c%2Cp%29%2Flog%28c%2Cb%29\"
\n" ); document.write( "
\n" );
