5. Exercise §6.5 #37. Let n e Z with n > 170. Prove that n is expressible as the sum of five squares of positive integers. (Hint: Express n - 169 = a² +b +² +&. If none of these squares are zero, then n = a² +b² +c² +d+13°. If exactly one of these squares is zero, say Continue.) d², then n = a² + b? +c²+5² + 12².

5. Exercise §6.5 #37. Let n € Z with n > 170. Prove that n is expressible as the sum of five squares
of positive integers. (Hint: Express n – 169 = a² + b² +² + &. If none of these squares are zero, then
n = a² +b² +c² + d²+ 13°. If exactly one of these squares is zero, say d², then n = a² + b² +c² +5² + 12².
