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.
Answer:
it would be 64-81 than answer devide by 6.
(12,756 kilometers) - (4,879 kilometers) = 7,877 kilometers
4x-3=5y
it would be : 4x - 5y = 3
Answer:
0
Step-by-step explanation:
-10 + 10
-10 and 10 are additive inverses, so when we add them, it is equal to zero
-10 + 10 = 0
