$\"sqrt%2820%29%2Asqrt%2840%29\"$ = $\"sqrt%28800%29\"$
\n" ); document.write( "therefore,
\n" ); document.write( " $\"sqrt%28800%29\"$ = $\"sqrt%28100%2A8%29\"$ \"factoring\"
\n" ); document.write( " = $\"sqrt%28100%2A4%2A2%29\"$ \"further factoring of 8 (4*2)\"
\n" ); document.write( "then = $\"10%2A2%2Asqrt%282%29\"$ \"the squares of $\"sqrt%28100%29\"$ and $\"sqrt%284%29\"$ gives 10 and 2\"
\n" ); document.write( " = $\"20%2Asqrt%282%29\"$ \r
\n" ); document.write( "\n" ); document.write( "Hence factoring $\"sqrt%2820%29%2Asqrt%2840%29\"$ will give $\"20%2Asqrt%282%29\"$ . \n" ); document.write( "

\n" );
