Correct Answer Marked Wrong

(3^2017)^2-(3^2015) / (3^2018)^2 - 3^2016)^2

I chose 1/9 as the answer, and so did the author, but the computer said it was wrong. This should be corrected!

#Algebra

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Thanks for pointing it out. We have accidentally changed the answer. I've updated the answer. Those who previously answered $\frac19$ has been marked correct.

In the future, if you have concerns about a problem's wording/clarity/etc., you can report the problem. See how here.
