Answer:
Explanation:
Use the laws of exponents, specifically the law for division.
When dividing, the exponents are subtracted.
For example,

Now let's do an example where the exponent will equal zero.

Now let's see why this equals 1. If you actually solve
it equals 25. So, let's solve the numerator and denominator and simplify.

As you can see, an exponent of 0 represents having the same number in the numerator and denominator, which when solved it equals 1.
