compare : log 2.56, log0.256 and log 25600 |
Answer» Solution :In the log table , we locate 25 in the first column, in this row, in the column under 4 we FIND 0.4048 . As done in the carlier example , the same line as before gives the mantissa of logarithms of all numbers which begin with 25. from this line we pick out the mantissa which is located in the column NUMBERED 4. this gives 4048 as the mantissa for all numbers whose signifiant DIGITS are 254. log 2.54 = 0.4084 log 0.254= `overline1.4048` log 25400= 4.4048 |
