rationalize the numerator and simplify
\n" ); document.write( " $\"%287-Sqrt%2810%29%29%2F2\"$
\n" ); document.write( "Multiply by the conjugate of the numerator over itself, (equals 1)
\n" ); document.write( " $\"%287-Sqrt%2810%29%29%2F2\"$ * $\"%287%2BSqrt%2810%29%29%2F%287%2Bsqrt%2810%29%29\"$ = $\"%2849-10%29%2F%282%287%2Bsqrt%2810%29%29%29\"$ = $\"39%2F%2814%2B2sqrt%2810%29%29\"$ \n" ); document.write( "

\n" );
