Question

Please may somebody evaluate 13 to the power of -2?

Answer 1

You should do `13*13` and put that as the denominator of `1`.

Explanation:

Because `13^(-2)` has a negative exponent, you must divide one by it to make it positive.

`13*13=169`

Divide one by this and you will get

`1/169` or `1/13^2`
