Log 3= 0,055 log 4= 0,065 Hitungla Log 3600 dan log 0,048

log3600=log9x4x100
             =2xlog3+log4+2xlog10
             =2x0,055+0,065+2x1
             =0,110+0,065+2
             =2,175
log0,048=log4+log4+log3+(-3)
              =0,065+0,065+0,055-3
              =0,185-3
              =-2,815
