Question type: Mathematical calculation
Solution:
20*lg√(100×((22.41*3.115156)^2+1)÷3.115156^2÷(0.04*3.115156^2+1)÷(0.25*3.115156^2+1)÷((422.86*3.115156)^2+1))
=20*lg√(100×(69.810646^2+1)÷3.115156^2÷(0.04*3.115156^2+1)÷(0.25*3.115156^2+1)÷((422.86*3.115156)^2+1))
=20*lg√(100×4874.526295÷3.115156^2÷(0.04*3.115156^2+1)÷(0.25*3.115156^2+1)÷((422.86*3.115156)^2+1))
=20*lg√(100×4874.526295÷3.115156^2÷1.388168÷(0.25*3.115156^2+1)÷((422.86*3.115156)^2+1))
=20*lg√(100×4874.526295÷3.115156^2÷1.388168÷3.426049÷((422.86*3.115156)^2+1))
=20*lg√(100×4874.526295÷3.115156^2÷1.388168÷3.426049÷(1317.274866^2+1))
=20*lg√(100×4874.526295÷3.115156^2÷1.388168÷3.426049÷1735214.072595)
=20*lg√0.006087
=20*lg0.078019
=20*-1.1078
=-22.156
Answer:20*lg√(100×((22.41*3.115156)^2+1)÷3.115156^2÷(0.04*3.115156^2+1)÷(0.25*3.115156^2+1)÷((422.86*3.115156)^2+1))=-22.156
