Work: Calculate the value of equation -300+(23.75-67.5)/1.1+(23.75-75)/1.1^2+(57.5-112.5)/1.1^3 .
Question type: Mathematical calculation
Solution:
-300+(23.75-67.5)/1.1+(23.75-75)/1.1^2+(57.5-112.5)/1.1^3
=-300+(-43.75)/1.1+(23.75-75)/1.1^2+(57.5-112.5)/1.1^3
=-300+(-43.75)/1.1+(-51.25)/1.1^2+(57.5-112.5)/1.1^3
=-300+(-43.75)/1.1+(-51.25)/1.1^2+(-55)/1.1^3
=-300+-43.75/1.1+(-51.25)/1.21+(-55)/1.1^3
=-300+-43.75/1.1+(-51.25)/1.21+(-55)/1.331
=-300+(-39.772727)+(-51.25)/1.21+(-55)/1.331
=-300+-39.772727+(-42.355372)+(-55)/1.331
=-300+-39.772727+(-42.355372)+(-41.322314)
=-339.772727+(-42.355372)+(-41.322314)
=-382.128099+(-41.322314)
=-423.450413
Answer:-300+(23.75-67.5)/1.1+(23.75-75)/1.1^2+(57.5-112.5)/1.1^3=-423.450413
