How to Use log Table

1. Find the Value of log(19.67)

Step 1: first identify the Characteristic Part and Mantissa part of the given algorithm. we want to find the 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 columns 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 is given = 4

15 = Check the Value in the 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 is given = 2

15 = Check the Value in the 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 is given = 1

15 = Check the Value in the 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

1. log_x(ab) = log_xa+ log_xb [Product Rule]
2. log_x(a/b) = log_xa – log_xb [Quotients Rule]
3. log_a x = log_b x * log_a b
4. log_b x = log_a x * log_a b
5. log_b xⁿ = n log_b x [Power Rule]
6. 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.
