[1/1 Formula]
Work: Calculate the value of equation 200/(1+0.1)+800/(1+0.1)^2+(-800)/((1+0.1))^3-200 .
Question type: Mathematical calculation
Solution:
200/(1+0.1)+800/(1+0.1)^2+(-800)/((1+0.1))^3-200
=200/1.1+800/(1+0.1)^2+(-800)/((1+0.1))^3-200
=200/1.1+800/1.1^2+(-800)/((1+0.1))^3-200
=200/1.1+800/1.1^2+(-800)/((1+0.1))^3-200
=200/1.1+800/1.1^2+(-800)/(1.1)^3-200
=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)-200
=842.975207+(-601.051841)-200
=241.923366-200
=41.923366
Answer:200/(1+0.1)+800/(1+0.1)^2+(-800)/((1+0.1))^3-200=41.923366
