$\"+4%5E%283x%29+=+7%5E%28x%2B1%29+\"$
\n" ); document.write( "3x*log(4) = (x+1)*log(7)
\n" ); document.write( "x*log(64) = x*log(7) + log(7)
\n" ); document.write( "x*log(64) - x*log(7) = log(7)
\n" ); document.write( "x*(log(64) - log(7)) = log(7)
\n" ); document.write( "x = log(7)/(log(64/7)
\n" ); document.write( "x =~ 0.87932
