Which expression is equivalent to
r^9/r^3

r^6

Step-by-step explanation:

When you are dividing numbers (or variables) with powers, if the base are the same, you are essentially subtracting the powers. In this case, the base is the variable, r. To answer, simply subtract 9 with 3:

r^(9 - 3) = r^6

r^6 is your answer.
