Log(4)+log(2)-log(5)
Otrada [13]

                       log(4)  +  log(2)  -  log(5)

                 =    log(2²) +  log(2)  -  log(5)

                 =    2 log(2) + log(2)  -  log(5)

                 =      3 log(2)  -  log(5)

                 =      log(2³)  -  log(5)

                 =        log (2³/5)

                 =        log (8/5)

                 =        log (1.6)  =  0.2041...  (rounded)
