〖1/1算式〗
作业:求算式 105×((1+0.0345)^1-1)+(2100+220+20+21.5+74)×((1+0.0345)^0.5-1) 的值.
题型:数学计算
解:
105×((1+0.0345)^1-1)+(2100+220+20+21.5+74)×((1+0.0345)^0.5-1)
=105×(1.0345^1-1)+(2100+220+20+21.5+74)×((1+0.0345)^0.5-1)
=105×0.0345+(2100+220+20+21.5+74)×((1+0.0345)^0.5-1)
=105×0.0345+2435.5×((1+0.0345)^0.5-1)
=105×0.0345+2435.5×(1.0345^0.5-1)
=105×0.0345+2435.5×0.017104
=3.6225+2435.5×0.017104
=3.6225+41.656792
=45.279292 答案:105×((1+0.0345)^1-1)+(2100+220+20+21.5+74)×((1+0.0345)^0.5-1)=45.279292你的问题在这里没有得到解决?请到 热门难题 里面看看吧!
