16^x*64^2x-2=64
\n" ); document.write( "4^2x*4^3(2x-2)=4^3
\n" ); document.write( "4^2x*4^6x-6=4^3
\n" ); document.write( "2x+6x-6=3
\n" ); document.write( "8x-6=3
\n" ); document.write( "8x=3+6
\n" ); document.write( "8x=9 ,divide both sides by 8
\n" ); document.write( "8x/8=9/8
\n" ); document.write( "x=9/8
\n" ); document.write( "
