A mobile base station (BS) in an urban environment has a power measurement of 35 µW at 180 m. Assuming the propagation follows the inverse 4th power law, what is a reasonable power value in W, to assume at a distance of 540 m from the BS? Express your answer in scientific notation to 2 decimal places.

Note: I do not know if this is correct

 

35 x 10^-6  =  k/ (180^4)      k= 36741.6

 

Power = 36741.6 / 5404 =  432 .09   nanowatts       or         4.32 x 10-7 watts
