Explanation:
We are given the following expression and we are to determine whether it is to be multiplied or divided and perform that operation on it accordingly:
![\frac {x ^ {-8} } { x ^ {-7}}](https://img.qammunity.org/2020/formulas/mathematics/high-school/flebapqwylsdv9dmr7nqz44yrusdq67t6m.png)
The given expression indicates that the two terms are to be divided and we know that when two terms with same bases are divided, their exponents are subtracted.
![x^((-8)-(-7)) = x^(-1)](https://img.qammunity.org/2020/formulas/mathematics/high-school/g0e7drxd1k6zov669ngkd74spf0jji7hrg.png)
Therefore, the simplified answer is
