Okay from
\n" ); document.write( "5^x = 3 * 4^x
\n" ); document.write( "take the log and get
\n" ); document.write( "log 5^x = log (3 * 4^x)
\n" ); document.write( "now apply power rule and multiplication rule and get
\n" ); document.write( "x*log 5 = log 3 + x*log 4
\n" ); document.write( "x*log 5 - x*log 4= log 3
\n" ); document.write( "x(log 5 - log 4)= log 3
\n" ); document.write( "x = log 3 / (log 5 - log 4)
\n" ); document.write( "then use your calculator \n" ); document.write( "
