Question

how to use log table in logarithms

Answer 1

there are different properties to solve them....You are supposed to use a log table when you require some special values of log,i.e.(log base 2,4,6,.....any other number....)

Answer 2

There are different properties for log to solve them..
You can use log table to find the value of log...
like log base 2, log base 4, log base 5 etc.

So to use log table in logarithm you can use this 4 simple steps.

1.Choose the correct table: To find
$log_{a}(n)$
you will need a log base a table.
$where \: a = 123.... \\ like \: log_{a}() = log_{10}() ..or \: etc.$
Most log tables are for log base 10, which are called common log.


2.Find the correct cell:Look for the cell value of the following intersections, ignoring all decimal places.

3.
$example = \\ log_{10}(31.62) \\ row = 31...column = 6....cell \: value = 0.4997.$
3. Use smaller chart for precise number.

4. prefix a decimal point:The log table only tells you the portion of your answer after the decimal point.

5.Find the integer portion.
