You can follow below steps to view log table

1- Choose the correct table. To find loga(n), you'll need a loga table. Most log tables are for base-10 logarithms, called "common logs."

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

• Row labeled with first two digits of n
• Column header with third digit of n

3- Use smaller chart for precise numbers. Some tables have a smaller set of columns on the right side of the chart. Use these to adjust answer if n has four or more significant digits:

• Stay in same row
• Find small column header with fourth digit of n
• Add this to previous value

4- Prefix a decimal point. The log table only tells you the portion of your answer after the decimal point. This is called the "mantissa."

5- Find the integer portion. Also called the "characteristic". By trial and error, find integer value of p ap<n{\displa
