〖1/1算式〗
作业:求算式 (80-54)/(1+10%)+(80-54)/(1+10%)*2+((80-54)+5)/(1+10%)*3 的值.
题型:数学计算
解:
(80-54)/(1+10%)+(80-54)/(1+10%)*2+((80-54)+5)/(1+10%)*3
=26/(1+10%)+(80-54)/(1+10%)*2+((80-54)+5)/(1+10%)*3
=26/1.1+(80-54)/(1+10%)*2+((80-54)+5)/(1+10%)*3
=26/1.1+26/(1+10%)*2+((80-54)+5)/(1+10%)*3
=26/1.1+26/1.1*2+((80-54)+5)/(1+10%)*3
=26/1.1+26/1.1*2+(26+5)/(1+10%)*3
=26/1.1+26/1.1*2+31/(1+10%)*3
=26/1.1+26/1.1*2+31/1.1*3
=23.636364+26/1.1*2+31/1.1*3
=23.636364+23.636364*2+31/1.1*3
=23.636364+47.272728+31/1.1*3
=23.636364+47.272728+28.181818*3
=23.636364+47.272728+84.545454
=70.909092+84.545454
=155.454546 答案:(80-54)/(1+10%)+(80-54)/(1+10%)*2+((80-54)+5)/(1+10%)*3=155.454546你的问题在这里没有得到解决?请到 热门难题 里面看看吧!
