(1+0.1)+(2+0.1*2)+(3+0.1*3)+...+(99+0.1*99)+(100+0.1*100)等于几?

(1+0.1)+(2+0.1*2)+(3+0.1*3)+...+(99+0.1*99)+(100+0.1*100)等于几?
(1+0.1)+(2+0.1*2)+(3+0.1*3)+...+(99+0.1*99)+(100+0.1*100)等于几?

(1+0.1)+(2+0.1*2)+(3+0.1*3)+...+(99+0.1*99)+(100+0.1*100)等于几?
原式=(1+2+3+……+100)+(0.1*1+0.1*2+0.1*3+0.1*4+……+0.1*100)=(101*50)+(1.1*50)=5050+55=5105 所以:原式等于5105.
