You can put this solution on YOUR website!
9^(x-5)=81^(x-7)
\n" ); document.write( "9^(x-5)=9^2(x-7)
\n" ); document.write( "since the bases are same
\n" ); document.write( "x-5 = 2(x-7)
\n" ); document.write( "x-5=2x-14
\n" ); document.write( "2x-x=14-5
\n" ); document.write( "x=9
\n" ); document.write( "...
