(1/8+1/24+1/48+1/80+1/120+1/168+1/224)*64=?
(1/8+1/24+1/48+1/80+1/120+1/168+1/224)*64=
1/(1/18+1/24+1/30)=1/(20/360+15/360+6/360) =1/(41/360) =8.32
(360-X)*(1-1/4)=x-24
42x(8/1+24/1+48/1+80/1+120/1+168/1)=?
1*2*3*4+1=24+1=5*5 2*3*4*5+1=120+1=11*11 3*4*5*6+1=360+1=19*
(1/8+1/24+1/48+1/80+1/120+1/168+1/224+1/288)×128=_____.
