(1/(r^2 −4))=(1/(4(r−2)))−(1/(4(r+2))) ⇒Σ_(r=3) ^(100) (1/(r^2 −4))=(1/4)Σ((1/(r−2))−(1/(r+2)))=(1/4)(1+(1/2)+(1/3)+(1/4)−(1/(99))−(1/(100))−(1/(101))−(1/(102))) x=25(1+(1/2)+(1/3)+(1/4)−(1/(99))−(1/(100))−(1/(101))−(1/(102)))=51.088.... [x]=51

1r2−4=14(r−2)−14(r+2)⇒∑r=31001r2−4=14Σ(1r−2−1r+2)=14(1+12+13+14−199−1100−1101−1102)x=25(1+12+13+14−199−1100−1101−1102)=51.088....[x]=51
