Following the guidelines of the CTE, pretend that you were calculating the above expression step-by-step. You could then use the following procedure:

1. Compute the quantities (3x-1) and (x²-e^x).

2. Divide the first answer by the second.

3. Raise the quotient to the power -4.

Since the last operation you would perform is raising a number to a power, the CTE tells us that the given expression is a power.
