[1/1 Formula]
Work: Calculate the value of equation -500+100/1.1+200/1.1^2+300/1.1^3+400/1.1^4 .
Question type: Mathematical calculation
Solution:
-500+100/1.1+200/1.1^2+300/1.1^3+400/1.1^4
=-500+100/1.1+200/1.21+300/1.1^3+400/1.1^4
=-500+100/1.1+200/1.21+300/1.331+400/1.1^4
=-500+100/1.1+200/1.21+300/1.331+400/1.4641
=-500+90.909091+200/1.21+300/1.331+400/1.4641
=-500+90.909091+165.289256+300/1.331+400/1.4641
=-500+90.909091+165.289256+225.39444+400/1.4641
=-500+90.909091+165.289256+225.39444+273.205382
=-409.090909+165.289256+225.39444+273.205382
=-243.801653+225.39444+273.205382
=-18.407213+273.205382
=254.798169
Answer:-500+100/1.1+200/1.1^2+300/1.1^3+400/1.1^4=254.798169
