You can put this solution on YOUR website!
As a general rule, I can say that
\n" ); document.write( " $\"sqrt%28a%2Ab%5Ec%29+=+sqrt%28a%29%2Ab%5E%28c%2F2%29\"$
\n" ); document.write( "Suppose the problem was
\n" ); document.write( " $\"4b%5E4\"$
\n" ); document.write( "The square root is
\n" ); document.write( " $\"2b%5E2\"$ since( $\"2%2Ab%2Ab\"$ )x( $\"2%2Ab%2Ab\"$ ) = $\"4b%5E4\"$
\n" ); document.write( "Your problem is
\n" ); document.write( " $\"sqrt%2864b%5E48%29\"$
\n" ); document.write( " $\"sqrt%2864%29+=+8\"$
\n" ); document.write( " $\"sqrt%28b%5E48%29+=+b%5E24\"$ , so
\n" ); document.write( " $\"sqrt%2864b%5E48%29+=+8b%5E24\"$ \n" ); document.write( "

\n" );
