Work: Calculate the value of equation -40+20*(1-1.2^(-5))+20/(1.2^5) .
Question type: Mathematical calculation
Solution:
-40+20*(1-1.2^(-5))+20/(1.2^5)
=-40+20*(1-1.2^(-5))+20/(1.2^5)
=-40+20*0.598122+20/(1.2^5)
=-40+20*0.598122+20/2.488319999999999
=-40+11.96244+20/2.488319999999999
=-40+11.96244+8.037551
=-28.03756+8.037551
=-20.000009
Answer:-40+20*(1-1.2^(-5))+20/(1.2^5)=-20.000009
