Answer:
6^4
(None of the options are correct, unless letter E is actually 6^4 instead of 64)
Explanation:
The objective of the question is to simplify the expression:
(6^5-6^4)/5
So we need to make this expression be in its simplest form, which we can do making the following operations:
(6^5-6^4)/5
= (6*(6^4)-(6^4))/5
= 5*(6^4)/5
= 6^4
None of the options showed has this expression or a similar expression that have the same value.
Maybe letter E is written wrong: instead of 64, it would be 6^4, so the correct option would be letter E.
