\n" ); document.write( "Consider this calculation:

\n" ); document.write( "\"%28sqrt%28a%29%2Bsqrt%28b%29%29%5E2\"

\n" ); document.write( "= \"%28a%2Bb%29%2B2sqrt%28ab%29\"

\n" ); document.write( "So if you have an expression in the form \"%28a%2Bb%29%2B2sqrt%28ab%29\", then its square root is \"sqrt%28a%29%2Bsqrt%28b%29\".

\n" ); document.write( "To find the square root of the given expression, you need to put it in exactly that form -- specifically, you need the radical part to be \"2sqrt%28ab%29\". So

\n" ); document.write( "

\n" ); document.write( "And then the task is to find the numbers a and b for which a+b=32 and ab=135.

\n" ); document.write( "Those numbers are 27 and 5, so

\n" ); document.write( "\"sqrt%2832-6sqrt%2815%29%29+=+sqrt%2827%29-sqrt%285%29+=+3sqrt%283%29-sqrt%285%29\"

\n" ); document.write( "
