100-(1+1/2+1/3+1/4+...+1/100)= (1+1+1+..+1)+(1+1/2+1/3+1/4+...+1/100) = (1-1)+(1-1/2)+(1-/3)+...+(1-1/100)
= 1/2+2/3+3/4+...+99/100 (đpcm)
chứng minh : 100- (1+1/2+1/3+1/4+...+1/100)=1/2+2/3+3/4+...+99/100
Chứng minh rằng 100- ( 1 + 1/2 +1/3 +...+1/100) = 1/2 +2/3 +3/4 +...+99/100
chứng minh rằng 100-(1+1/2+1/3+...+1/100)=1/2+2/3+3/4+...+99/100
