Answer:
We subtract exponents when diving powers with the same base because they eventually get canceled out when written in expanded form.
Step-by-step explanation:
For example, if we expand the given fractions: 
10^3/10^1 = 1000/10 = 100 = 10^2
Now, if we subtract the exponents we get the same result. 
10^3-1 = 10^2
So, a^m/a^n = a^m-
n is one of the exponent rules which saves time and makes calculation easier.
 
        
             
        
        
        
Midpoint Formula: (

Midpoint = (

)
Midpoint = (

, -4)
So, the midpoint of the endpoints (-4,-3) and (7,-5) is (

, -4).
