Hi in this i am going to share with you all one of the best and important Logarithm and Antilogarithm Table. you can download **Log Table **PDF with Antilogarithm chart.

we have provided the **log** on this page along with table definition you all can download complete table from the given link below.

In mathematics, the logarithm table is used to find the value of the logarithmic function. The simplest way to find the value of the given logarithmic function is by using the Logarithm table. Here the definition of the logarithmic function and procedure to use the logarithm table is given in detail.

log Table use in physics chemistry and mathematics and others many subjects.

### How to Use log Table

**1. Find the Value of log(19.67)**

**Step 1: **first identify the Characteristic Part and Mantissa part of given algorithm. we want to find base 10 log of **19.67** value.

Characteristic Part = 19

Mantissa part = 67

**Step 2: **19 lies between 10 and 99 so its log will lie between 1.

or just use (total characteristic digit-1) = (2-1) = 1

**Step 3:** Now look at the logarithm table using row number 19 to refer to column number 6 whose value will be **2923**.

**Step 4: **Now check the mean column no 7 whose value will be **16**.

Now just add both column no 6 and 7 value

**2923 + 16 = 2939**

the final answer value will be **1.2939**

**log(19.67)** = **1.2939**

**2. Find the value of log(1563)**

Total Digit are given = 4

15 = Check the Value in first column

6 column = 1931

3 column = 8

add both 1931+8=1939

or just use (total characteristic digit-1) = (4-1) = 3

final answer 3.1939

**log(1563) = 3.1939**

**3. Find the value of log(15.63)**

Total Digit are given = 2

15 = Check the Value in first column

6 column = 1931

3 column = 8

add both 1931+8=1939

or just use (total characteristic digit-1) = (1-1) = 0

final answer 1.1939

**log(15.63) = 1.1939**

**4. Find the value of log(1.563)**

Total Digit are given = 1

15 = Check the Value in first column

6 column = 1931

3 column = 8

add both 1931+8=1939

or just use (total characteristic digit-1) = (1-1) = 0

final answer 0.1939

**log(1.563) = 0.1939**

### Property of Log

**l**og_{x}(ab) = log_{x}a+ log_{x}b [Product Rule]- log
_{x}(a/b) = log_{x}a – log_{x}b [Quotients Rule] - log
_{a}x = log_{b }x * log_{a }b - log
_{b}x = log_{a }x * log_{a }b - log
_{b}x^{n }= n log_{b}x [Power Rule] - log(a+b)=loga+b/(2.42×a)

**Question:** Find the value of log(737) using Property of Log?

log(mn)=logm+logn

=log(737)=log(7.37×10 2 )

=log(7.37)+log(10 2 ) by using

=log(7.37)+2[log10 n =n]

=log(7+0.37)+2

Now applying the formula log(a+b)=loga+b/(2.42×a);

=log(7)+0.37/(2.42×7)+2

it comes out to be 2.867 which is the log value for 737.
