Question

(1/1)-²+(1/2)²+(1/3)-²+(1/4)²+(1/5)-²

Answer 1

${ \frac{1}{1} }^{ - 2} + { \frac{1}{2} }^{2} + { \frac{1}{3} }^{ - 2} + { \frac{1}{4} }^{2} + { \frac{1}{5} }^{ - 2} \\ {1}^{2} + \frac{1}{4} + {3}^{2} + \frac{1}{16} + {5}^{2} \\ 1 + \frac{1}{4} + 9 + \frac{1}{16} + 25 \\ 35 + \frac{5}{16} \\ \frac{565}{16}$
