(Q) What is the characteristic of the logarithm of 0.0000134 ?

A) -9
B) -7
C) -5
D) -4

View Answer

C) -5

Explanation :
The characteristic of the logarithm of a number whose integral part consists of n digits is n-1.
Therefore, we have the following rule:
The characteristic of the logarithm of a number greater than 1 is positive and is one less than the number of digits in an integral part of the number.
We have to tell the characteristic of the logarithm of 0.0000134.
log (0.0000134):
Because there are four zeros between the decimal point and the first significant digit, therefore, the characteristic is -5.
