Since the bases are the same you can subtract the exponents. All you have to do is 5-2, which is 3 therefore the answer is x^3.
Answer is -11. use the given functions to set up & simplify f(3)
18 wrist bands and 12 belts.
You can solve this using the following system of equations.
x + y = 30
5.5x + 8.75y = 204
