You can put this solution on YOUR website!
(1/3)^x+1 = 9^x
\n" ); document.write( "you made a mistake making the bases the same:
\n" ); document.write( "9^-2=1/81 so that doesn't work
\n" ); document.write( "you want
\n" ); document.write( "9^-(1/2)=1/3
\n" ); document.write( "So you get:
\n" ); document.write( "9^-(1/2)(x+1) = 9^x
\n" ); document.write( "-(1/2)(x+1) simplifies to -1/2x-1/2 since you have to distribute the negative 1/2\r
\n" ); document.write( "\n" ); document.write( "-(1/2)x-1/2=x
\n" ); document.write( "Multiply both sides by 2 to clear the fraction
\n" ); document.write( "-x-1=2x
\n" ); document.write( "add x to both sides
\n" ); document.write( "-1=3x
\n" ); document.write( "divide both sides by 3
\n" ); document.write( "x=-1/3\r
\n" ); document.write( "\n" ); document.write( "Difficult problem!
\n" ); document.write( "
\n" );
