Question

3. In logarithmic form logb A,the value of B cannot be _______​

Answer 1

Answer:

Positive is the answer

Answer 2

Given:

In the logarithmic form of $log_{b}A$

To Find:

The value of b?

Solution:

To find the range or value of b first we need to understand what a logarithm is  a reverse function of exponential function lets see in equation form

                                             $b^x=A$

this is an exponential function and when we convert it in logarithm form

                                             $x=log_{b}A$

so because of this, the value of b can only be positive and not negative or 0.

we can also observe it with a graph.

As we can see in the graph that it never touches 0 and doesn't go beside that.

Hence, the value of b cannot be 0 or negative numbers.
