\n" ); document.write( "\n" ); document.write( "When a problem of this type says that N varies jointly as the square root of \"p\",\r
\n" ); document.write( "\n" ); document.write( "it is usually assumed that p is non-negative real number - then the real value $\"sqrt%28p%29\"$ does exist.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "With negative \"p\" (as -4 in your question), square root of negative \"p\" does not exist as a real number.\r
