(1+0.11+0.13+0.17)*(0.11+0.13+0.17+0.19)-(1+0.11+0.13+0.17+0.19)*(0.11+0.13+0.17)这题的解法是什么?(1+0.11+0.

(1+0.11+0.13+0.17)*(0.11+0.13+0.17+0.19)-(1+0.11+0.13+0.17+0.19)*(0.11+0.13+0.17)这题的解法是什么?
(1+0.11+0.13+0.17)*(0.11+0.13+0.17+0.19)-(1+0.11+0.13+0.17+0.19)*(0.11+0.13+0.17)
这题的解法是什么?

(1+0.11+0.13+0.17)*(0.11+0.13+0.17+0.19)-(1+0.11+0.13+0.17+0.19)*(0.11+0.13+0.17)这题的解法是什么?
首先把原题中的加法算出
得 1.41*0.6-1.6*0.41
=(1+0.41)*0.6-(1+0.6)*0.41
=0.41*0.6-0.6*0.41+1*0.6-1*0.41
=0+0.6-0.41
=0.19

等于0.19

把括号里面的1提出来,不知道这样说能理解么
