Work: Calculate the value of equation (12000×380+300×200^3)/(380+200)^3+3/(380+200)*(1/(12000×380)+1/(300×200))^(-1) .
Question type: Mathematical calculation
Solution:
(12000×380+300×200^3)/(380+200)^3+3/(380+200)*(1/(12000×380)+1/(300×200))^(-1)
=2404560000/(380+200)^3+3/(380+200)*(1/(12000×380)+1/(300×200))^(-1)
=2404560000/580^3+3/(380+200)*(1/(12000×380)+1/(300×200))^(-1)
=2404560000/580^3+3/580*(1/(12000×380)+1/(300×200))^(-1)
=2404560000/580^3+3/580*(1/4560000+1/(300×200))^(-1)
=2404560000/580^3+3/580*(1/4560000+1/60000)^(-1)
=2404560000/580^3+3/580*0.000017^(-1)
=2404560000/580^3+3/580*0.000017^(-1)
=2404560000/195112000+3/580*0.000017^(-1)
=2404560000/195112000+3/580*58823.52941176470631
=12.323999+3/580*58823.52941176470631
=12.323999+0.005172*58823.52941176470631
=12.323999+304.235294
=316.559293
Answer:(12000×380+300×200^3)/(380+200)^3+3/(380+200)*(1/(12000×380)+1/(300×200))^(-1)=316.559293
