2.6×0.08+7.5×1.04=(2.5+0.1)×0.08+7.5×(1+0.04)=2.5×0.08+0.008+7.5+7.5×0.04=2.5×0.08+(10-2.5)×0.04+7.5+0.08=2.5×0.08+0.4-2.5×0.04+7.5+0.08=2.5×(0.08-0.04)+0.4+7.5+0.08=2.5×0.04+0.4+7.5+0.08=0.1+0.4+7.5+0.08=0.5+7.5+0.08=8+0.08=8.08

2.6*0.08+7.5*1.04
该式子具体计算过程如下:
2.6×0.08+7.5×1.04=0.208+7.8=8.008
不对
你把原题发给我看一下
简便计算
就是原题
2.6×0.08+7.5×1.04=(2.5+0.1)×0.08+7.5×(1+0.04)=2.5×0.08+0.008+7.5+7.5×0.04=2.5×0.08+(10-2.5)×0.04+7.5+0.08=2.5×0.08+0.4-2.5×0.04+7.5+0.08=2.5×(0.08-0.04)+0.4+7.5+0.08=2.5×0.04+0.4+7.5+0.08=0.1+0.4+7.5+0.08=0.5+7.5+0.08=8+0.08=8.08
错的啊
哎
答案都不对
中间那个0.008写成0.08了
2.6×0.08+7.5×1.04=2.6×0.04×2+7.5+7.5×0.04=0.04×(2.6×2+7.5)+7.5=0.04×12.7+7.5=0.508+7.5=8.008
