Work: Calculate the value of equation -200-100/1.1+400/1.1^2+300/1.1^3+200/1.1^4 .
Question type: Mathematical calculation
Solution:
-200-100/1.1+400/1.1^2+300/1.1^3+200/1.1^4
=-200-100/1.1+400/1.21+300/1.1^3+200/1.1^4
=-200-100/1.1+400/1.21+300/1.331+200/1.1^4
=-200-100/1.1+400/1.21+300/1.331+200/1.4641
=-200-90.909091+400/1.21+300/1.331+200/1.4641
=-200-90.909091+330.578512+300/1.331+200/1.4641
=-200-90.909091+330.578512+225.39444+200/1.4641
=-200-90.909091+330.578512+225.39444+136.602691
=-290.909091+330.578512+225.39444+136.602691
=39.669421+225.39444+136.602691
=265.063861+136.602691
=401.666552
Answer:-200-100/1.1+400/1.1^2+300/1.1^3+200/1.1^4=401.666552
