Answer:
[tex]x^{-1}[/tex]
Step-by-step 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:
[tex] \frac {x ^ {-8} } { x ^ {-7}} [/tex]
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.
[tex]x^{(-8)-(-7)} = x^{-1}[/tex]
Therefore, the simplified answer is [tex]x^{-1}[/tex].
