Question

What is the difference and what is their value?

Answer 1

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 $g^{4}$ = 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.
