〖1/1算式〗
作业:求算式 70/1.05+70/(1.05^2)+70/(1.05^3)+70/(1.05^4)-200/1.05^0 的值.
题型:数学计算
解:
70/1.05+70/(1.05^2)+70/(1.05^3)+70/(1.05^4)-200/1.05^0
=70/1.05+70/1.1025+70/(1.05^3)+70/(1.05^4)-200/1.05^0
=70/1.05+70/1.1025+70/1.157625+70/(1.05^4)-200/1.05^0
=70/1.05+70/1.1025+70/1.157625+70/1.21550625-200/1.05^0
=70/1.05+70/1.1025+70/1.157625+70/1.21550625-200/1
=66.666667+70/1.1025+70/1.157625+70/1.21550625-200/1
=66.666667+63.492063+70/1.157625+70/1.21550625-200/1
=66.666667+63.492063+60.468632+70/1.21550625-200/1
=66.666667+63.492063+60.468632+57.589173-200/1
=66.666667+63.492063+60.468632+57.589173-200
=130.15873+60.468632+57.589173-200
=190.627362+57.589173-200
=248.216535-200
=48.216535 答案:70/1.05+70/(1.05^2)+70/(1.05^3)+70/(1.05^4)-200/1.05^0=48.216535你的问题在这里没有得到解决?请到 热门难题 里面看看吧!
