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!

Answer:

The correct option is A) 1 over 5 to the 3rd power.

Explanation:

Consider the provided information.

5 to the 5th over 5 to the 8th

This can be written as:


(5^5)/(5^(8))

Now, use the property of exponent:
(a^m)/(a^n)=a^(m-n)

Use the above property to solve the provided expression.


5^(5-8)


5^(-3)

Negative exponent rule:
a^(-m)=(1)/(a^m)

Use the above rule as shown:


5^(-3)


(1)/(5^(-3))

Thus, the simplified form of the provided expression is
(1)/(5^(-3)).

Hence, the correct option is A) 1 over 5 to the 3rd power.
