In the log table, we locate 37 in the first column. In this row, in the column under 4, we find 5729. As in the earlier example, the same line as before gives the mantisa of logarithms of all numbers which begin with 37. From this line, we select the mantissa which is located in the column number 4. This gives 5729 as the mantissa for all numbers whose significant digits are 3, 7 and 4.
`therefore` log 3.74 = 0.5729
log 374000 = 5.5729 and
log 0.3740 = `bar(1)`.5729.
