Question

What is 1/39 written as a negative exponent other than -1? (i.e. Not 39^-1)

Answer 1

As far as I am aware, there is no other way to write `1/39` using an exponent and `39` other than `39^-1`.

Explanation:

You could write is as `(39^-2)^(1/2)=sqrt(1/39^2)=1/39`.
However, if you simplified that, it would still be `39^-1`.
