[1/1 Formula]
Work: Calculate the value of equation 30/(1+0.1)+30/(1+0.1)^2+30/(1+0.1)^3-72 .
Question type: Mathematical calculation
Solution:
30/(1+0.1)+30/(1+0.1)^2+30/(1+0.1)^3-72
=30/1.1+30/(1+0.1)^2+30/(1+0.1)^3-72
=30/1.1+30/1.1^2+30/(1+0.1)^3-72
=30/1.1+30/1.1^2+30/1.1^3-72
=30/1.1+30/1.21+30/1.1^3-72
=30/1.1+30/1.21+30/1.331-72
=27.272727+30/1.21+30/1.331-72
=27.272727+24.793388+30/1.331-72
=27.272727+24.793388+22.539444-72
=52.066115+22.539444-72
=74.605559-72
=2.605559
Answer:30/(1+0.1)+30/(1+0.1)^2+30/(1+0.1)^3-72=2.605559
