Answer 2

The correct statement from the options for logarithm to exponential conversion and vice versa is:

• Option A: The exponential equation and the logarithmic equation will have the same base.

What is logarithm ?

When you raise a number with an exponent, there comes a result.

Lets say you get

$a^b = c$

Then, you can write 'b' in terms of 'a' and 'c' using logarithm as follows

$b = \log_a(c)$

'a' is called base of this log function. We say that 'b' is the logarithm of 'c' to base 'a'

What are some basic properties of exponentiation?

If we have $a^b$  then 'a' is called base and 'b' is called power or exponent and we call it "a is raised to the power b" (this statement might change from text to text slightly).

Exponentiation is the process of raising some number to some power.

Checking all the options to see which one is correct:

• Option A: The exponential equation and the logarithmic equation will have the same base.

Its correct. In $a^b = c$, base is 'a', and in $b = \log_a(c)$ too, base is 'a', and these two things are same.

Thus, this option is correct.

• Option B: The answer of the logarithmic function is the base of the exponential function.

Its not correct.

$2^3 = 8 \implies log_2(8) = 3 \neq 2$

So answer of log wasn't the base 2 but exponent 3.

• Option C: The answer to the logarithmic equation is the same as the answer to the exponential function.

$a^b = c \implies log_a(c) = b$ = answer of logarithmic function

but $a^b = c$ = answer of exponential function. They are't same always.

Thus, this option is not correct.

• Option D: The base of the logarithmic function is what you are taking the log of in the logarithmic function.

In $a^b = c \implies \log_a(c) = b$, we're taking log of 'c', but base is 'b'. So this option is incorrect.

Thus, the correct statement from the options for logarithm to exponential conversion and vice versa is:

• Option A: The exponential equation and the logarithmic equation will have the same base.
