Work: Calculate the value of equation (12000×50^3+12000×80^3)/(50+80)^3+3/(50+80)*(1/(12000×50)+1/(12000×800))^(-1) .
Question type: Mathematical calculation
Solution:
(12000×50^3+12000×80^3)/(50+80)^3+3/(50+80)*(1/(12000×50)+1/(12000×800))^(-1)
=7644000000/(50+80)^3+3/(50+80)*(1/(12000×50)+1/(12000×800))^(-1)
=7644000000/130^3+3/(50+80)*(1/(12000×50)+1/(12000×800))^(-1)
=7644000000/130^3+3/130*(1/(12000×50)+1/(12000×800))^(-1)
=7644000000/130^3+3/130*(1/600000+1/(12000×800))^(-1)
=7644000000/130^3+3/130*(1/600000+1/9600000)^(-1)
=7644000000/130^3+3/130*0.000002^(-1)
=7644000000/130^3+3/130*0.000002^(-1)
=7644000000/2197000+3/130*0.000002^(-1)
=7644000000/2197000+3/130*500000
=3479.289941+3/130*500000
=3479.289941+0.023077*500000
=3479.289941+11538.5
=15017.789941
Answer:(12000×50^3+12000×80^3)/(50+80)^3+3/(50+80)*(1/(12000×50)+1/(12000×800))^(-1)=15017.789941
