Work: Calculate the value of equation 2*500*0.087^2/(sqrt(3)*0.1^2)-390*0.05^2/(0.1^2-0.05^2)*2 .
Question type: Mathematical calculation
Solution:
2*500*0.087^2/(sqrt(3)*0.1^2)-390*0.05^2/(0.1^2-0.05^2)*2
=2*500*0.087^2/(sqrt3*0.1^2)-390*0.05^2/(0.1^2-0.05^2)*2
=2*500*0.087^2/0.017321-390*0.05^2/(0.1^2-0.05^2)*2
=2*500*0.087^2/0.017321-390*0.05^2/0.0075*2
=2*500*0.007569/0.017321-390*0.05^2/0.0075*2
=2*500*0.007569/0.017321-390*0.0025/0.0075*2
=1000*0.007569/0.017321-390*0.0025/0.0075*2
=7.569/0.017321-390*0.0025/0.0075*2
=436.984008-390*0.0025/0.0075*2
=436.984008-0.975/0.0075*2
=436.984008-130*2
=436.984008-260
=176.984008
Answer:2*500*0.087^2/(sqrt(3)*0.1^2)-390*0.05^2/(0.1^2-0.05^2)*2=176.984008
