Answer 2

Answer:

The characteristic of the logarithm of $0.0000134$ is $-5$.

Step-by-step 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 $-5$.
