Work: Calculate the value of equation 12000*60^3+9000*80^3/(60+80)^3+3/140*(1/12000*60+1/9000*80)^-1 .
Question type: Mathematical calculation
Solution:
12000*60^3+9000*80^3/(60+80)^3+3/140*(1/12000*60+1/9000*80)^-1
=12000*60^3+9000*80^3/140^3+3/140*(1/12000*60+1/9000*80)^-1
=12000*60^3+9000*80^3/140^3+3/140*0.01386^-1
=12000*216000+9000*80^3/140^3+3/140*0.01386^(-1)
=12000*216000+9000*512000/140^3+3/140*0.01386^(-1)
=12000*216000+9000*512000/2744000+3/140*0.01386^(-1)
=12000*216000+9000*512000/2744000+3/140*72.150072150072148
=2592000000+9000*512000/2744000+3/140*72.150072150072148
=2592000000+4608000000/2744000+3/140*72.150072150072148
=2592000000+1679.300292+3/140*72.150072150072148
=2592000000+1679.300292+0.021429*72.150072150072148
=2592000000+1679.300292+1.546104
=2592001679.300292+1.546104
=2592001680.846396
Answer:12000*60^3+9000*80^3/(60+80)^3+3/140*(1/12000*60+1/9000*80)^-1=2592001680.846396
