Work: Calculate the value of equation 70/1.05+70/(1.05^2)+70/(1.05^3)+70/(1.05^4)-200 .
Question type: Mathematical calculation
Solution:
70/1.05+70/(1.05^2)+70/(1.05^3)+70/(1.05^4)-200
=70/1.05+70/1.1025+70/(1.05^3)+70/(1.05^4)-200
=70/1.05+70/1.1025+70/1.157625+70/(1.05^4)-200
=70/1.05+70/1.1025+70/1.157625+70/1.21550625-200
=66.666667+70/1.1025+70/1.157625+70/1.21550625-200
=66.666667+63.492063+70/1.157625+70/1.21550625-200
=66.666667+63.492063+60.468632+70/1.21550625-200
=66.666667+63.492063+60.468632+57.589173-200
=130.15873+60.468632+57.589173-200
=190.627362+57.589173-200
=248.216535-200
=48.216535
Answer:70/1.05+70/(1.05^2)+70/(1.05^3)+70/(1.05^4)-200=48.216535
