Answer:2, 1, (in place of x) and y2
Step-by-step explanation: Divide your base numbers, which are 18 and 9, so you get 2. Then because you're dividing with exponents you are just subtracting them. So x 2-2 (Imagine these as exponents) so you'd get x0. Next you'd do the same with y so you'd end up with y2. Because your exponent is 0 on x it equals one.
