do 4.5/1.25 because that is the unit rate. when you do that you get 3.6 miles in an hour
Answer: 
Step-by-step explanation:
For this exercise you need to remember the Power of a power property. This states that:

You know that the given expression
is used to determine points earned, and "n" represents the game level.
Therefore, knowing this, you can to substitute
into the expression
:

Finally, in order to simplify the expression for the
level, you must apply the Power of a power property mentioned before.
Therefore, you get:

Answer:

Step-by-step explanation:
For this case we have the following expression:

We need to remember that the natural log and the exponentiation with the base the euler number e are inverse operations, and if we apply exponentiation on both sides of the equation we got this:

We have the identity operator for this 

And that would be our final answer for this case.
