Check three of my answers to three different problems? Question #1: Evaluate x-3 for x = 2 My answer: 1/8. Question #2: Simplify 2a0. My Answer: 2. Question #3: Simplify (5/9)^- 2. My Answer: So here we can use the negative to flip around the fraction. So once we flip it around we get (9/5)^2. So the negative is gone, but the two is still there. So now we we can solve this with 9/5 * 9/5. We can multiply straight across for the top and get 81, for the bottom we multiply straight across and get 25. So the answer is 81/25.
