Work: Calculate the value of equation 20*lg(10/(4.4*((1+4.4^2))^0.5)) .
Question type: Mathematical calculation
Solution:
20*lg(10/(4.4*((1+4.4^2))^0.5))
=20*lg(10/(4.4*(20.36)^0.5))
=20*lg(10/(4.4*20.36^0.5))
=20*lg(10/19.853705)
=20*lg0.503684
=20*-0.297842
=-5.95684
Answer:20*lg(10/(4.4*((1+4.4^2))^0.5))=-5.95684
