You can put this solution on YOUR website!
9^(x)- 5(3^x) +6 =0 (hint let y = 3^x)\r
\n" ); document.write( "\n" ); document.write( "\"%283%5E2%29%5Ex-5%283%5Ex%29%2B6=0\"
\n" ); document.write( "\"%283%5Ex%29%5E2-5%283%5Ex%29%2B6=0\", There is a rule of exponents for that.
\n" ); document.write( "Your hinted substitution:
\n" ); document.write( "\"y%5E2-5y%2B6=0\", which is factorable into....
\n" ); document.write( "\"%28y-2%29%28y-3%29=0\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Either y=2 OR y=3
\n" ); document.write( "Reversing the substitution done,
\n" ); document.write( "Either \"3%5Ex=2\" Or \"3%5Ex=3\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Whatever base you want, find logarithms of both sides for each choice of solution.\r
\n" ); document.write( "\n" ); document.write( "\"log%283%5Ex%29=log%282%29\"
\n" ); document.write( "\"x%2Alog%283%29=log%282%29\"
\n" ); document.write( "\"highlight%28x=log%282%29-log%283%29%29\", I skipped a step. You might want that as \"highlight%28x=%28log%282%29%29%2F%28log%283%29%29%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Do similarly for the other choice.
\n" ); document.write( "
\n" );
