[1/1 Formula]
Work: Calculate the value of equation -200+200/1.1+800/1.1^2-800/1.1^3 .
Question type: Mathematical calculation
Solution:
-200+200/1.1+800/1.1^2-800/1.1^3
=-200+200/1.1+800/1.21-800/1.1^3
=-200+200/1.1+800/1.21-800/1.331
=-200+181.818182+800/1.21-800/1.331
=-200+181.818182+661.157025-800/1.331
=-200+181.818182+661.157025-601.051841
=-18.181818+661.157025-601.051841
=642.975207-601.051841
=41.923366
Answer:-200+200/1.1+800/1.1^2-800/1.1^3=41.923366
