Simplify 5 to the 5th over 5 to the 8th.

1 over 5 to the 3rd power
53
1 over 25
1 over 5 to the negative 3rd

5^5/5^8
First of all, to simplify this ,we need to know about Law of Exponent rule which is:
a^p/a^q
=a^p-q (a≠0)
Now, we just do the same thing with this:
5^5/5^8
=5^5-8
=5^-3
Also, to make this simple, apply this into another Law of Exponents which is:
a^-p
=1/a^p (a≠0)
To the same to this
5^-3
=1/5^3. As a result, 1 over 5 to the 3rd power is your final answer. Hope it help!
