The problem should be
\n" ); document.write( "2log[b]x-7log[b]y
\n" ); document.write( "=2logx-7logy (base b)
\n" ); document.write( "=log(x^2) -log(y^7) (using formula n[log(m)]for base b = log(m^n) for base b )
\n" ); document.write( "=logb[(x^2)/(y^7)] (where b here is the base)
\n" ); document.write( "
\n" );
