〖1/1算式〗
作业:求算式 -2500-2000/(1+0.19)+1200×((1+0.19)^9-1)÷0.19÷(1+0.19)^9÷(1+0.19) 的值.
题型:数学计算
解:
-2500-2000/(1+0.19)+1200×((1+0.19)^9-1)÷0.19÷(1+0.19)^9÷(1+0.19)
=-2500-2000/1.19+1200×((1+0.19)^9-1)÷0.19÷(1+0.19)^9÷(1+0.19)
=-2500-2000/1.19+1200×(1.19^9-1)÷0.19÷(1+0.19)^9÷(1+0.19)
=-2500-2000/1.19+1200×3.785449÷0.19÷(1+0.19)^9÷(1+0.19)
=-2500-2000/1.19+1200×3.785449÷0.19÷1.19^9÷(1+0.19)
=-2500-2000/1.19+1200×3.785449÷0.19÷1.19^9÷1.19
=-2500-2000/1.19+1200×3.785449÷0.19÷4.785448563124473÷1.19
=-2500-1680.672269+1200×3.785449÷0.19÷4.785448563124473÷1.19
=-2500-1680.672269+4542.5388÷0.19÷4.785448563124473÷1.19
=-2500-1680.672269+23908.098947÷4.785448563124473÷1.19
=-2500-1680.672269+4995.999567÷1.19
=-2500-1680.672269+4198.318964
=-4180.672269+4198.318964
=17.646695 答案:-2500-2000/(1+0.19)+1200×((1+0.19)^9-1)÷0.19÷(1+0.19)^9÷(1+0.19)=17.646695你的问题在这里没有得到解决?请到 热门难题 里面看看吧!
