Question

Someone please answer this

Answer 1

Answer:

So the answer is just 7

Step-by-step explanation:

Let's do the number first.

21/3 = 7 so the answer will contain a 7.

I wonder what the best way to do e^3 is. Here' one way.

e^3 / e^3 = 1 which is just the answer. but suppose e = 5

Then you have (5*5*5)/(5*5*5) = 125/125

anything divided by itself = 1

so 125/125  = 1

A third way you could do it is like this

e^3/e^3 = e^3 * e- 3

Rule when you move anything (except zero) up from the denominator up to the numerator the power becomes the opposite of what it was.

Rule 1a: when you move anything (except 0) down to the denominator from the numerator the sign becomes the opposite to what it was.

Now you can add the powers

e^(3 - 3) = e^0 = 1

Answer 2

Answer:

7

Step-by-step explanation:

When dividing exponents, you subtract them.

First divide the coefficients, 21 and 3. This is equal to 7.

Now you have e^3 and e^3, and to divide exponents you subtract them, so e^3 - ^3 = e^0.

Anything to the 0th power is equal to 1, so you have 7 * 1 which is equal to 7.

Therefore the final and correct answer is just 7.
