Question

Write the given equation in exponential form.


log7 = 3

Answer 1

For this case we have that by definition of logarithmic properties that, the expression

`log_ {b} (a) = c` is equivalent to:

`b ^ c = a`

Then, we have the following expression:

`log_ {7} () = - 3`

It can be equivalent to:

`7 ^ {- 3} =`

Answer:

The correct option is option A

`7 ^ {-3}`
