Simplify:
\n" ); document.write( "\"-3sqrt%28180%29-7sqrt%2845%29\" First, rewrite both radicands.
\n" ); document.write( "\"-3sqrt%2836%2A5%29-7sqrt%289%2A5%29\" Now take the square root of the perfect squares: \"sqrt%2836%29+=+6\" and \"sqrt%289%29+=+3\" so...
\n" ); document.write( "\"-3%2A6sqrt%285%29-7%2A3sqrt%285%29\" Simplify.
\n" ); document.write( "\"-18sqrt%285%29-21sqrt%285%29\" Combine.
\n" ); document.write( "\"-39sqrt%285%29\"
\n" ); document.write( "
\n" );
