Answer:
Look below.
Step-by-step explanation:
For one, g+g+g+g does not equal g^4. That equals g·g·g·g.
But like you said, 4g = g·g·g·g as well, so shouldn't they be equal?
The answer is more simple than you might expect:
We'll do the second one first. I don't know why, that is just how it is going to be done.
Let's assign a value to 'g'. We'll call it g = 3.
3 to the 4th power is
1) 3·3 = 9
2) 9·3 = 27
3) 27·3 = 81.
So = 81.
But, you probably figured out, with g = 3, that 4g = 12, since 3·4 = 12.
Obviously, 81 ≠ 27, meaning these are not the same, and that is the main difference.
