$\"sqrt%2820%2F5%29+-+1%2Fsqrt%285%29\"$
\n" ); document.write( " $\"sqrt%2820%29%2Fsqrt%285%29+-+1%2Fsqrt%285%29\"$ ....... $\"sqrt%2820%29\"$ we can write as $\"sqrt%284%2A5%29+=+2+sqrt%285%29\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"2sqrt%285%29%2Fsqrt%285%29+-+1%2Fsqrt%285%29\"$ ..............eliminate $\"sqrt%285%29\"$ in first term, and we will have\r
\n" ); document.write( "\n" ); document.write( " $\"2+-+1%2Fsqrt%285%29\"$ ...........common denominator is $\"sqrt%285%29\"$
\n" ); document.write( " $\"%282sqrt%285%29-1%29%2Fsqrt%285%29\"$ \r
