The "nth" root in equation builder is quite a pain. I work for an instructor and I type her classes into Canvas. Nth root has a programming error. I have emailed about the problem and I was told to post in the forum for review. Here is my post. The programming for nth root is in need of change. Here is the problem:

I type: third root of 26.

Html: [3]{26}

At the end of my problem I have an option to "enter" answer #3. This being from [3] which actually belongs to my third root. I have been fixing this myself by replacing [ ] with { } everytime. However, this is becoming quite tedious today after 23 equations in a row. I hope this discussion thread helps.

I was in a rush this morning and running late. On the way to work, it hit me what you were doing. You're editing the HTML directly to modify the image tag. The reason the cube root still showed up as a cube root was because you weren't changing the image itself.

To be clear, everything I was talking about was done inside the equation editor so that you don't have to go in to HTML source at all.

Replacing the [3] with {3} doesn't fix the issue, either, as screen readers and other assistive technology will read that as the square root of 3 with an implied times 26. That's bad math notation, because we all write it as 26 sqrt 3

I did also notice on yours that the cube root was by itself and the 26 wasn't under the vinculum. If you do what I did, go intp the math editor, switch to advanced mode, and type

\sqrt[ 3]{26}then it will come out looking right and won't show up as a placeholder because of the extra space after the left bracket.As for the other issue, anyone using Canvas can click the Help button at the top right and Report a problem (unless your school has it turned off). If you're in the Canvas Community, I think membership to most groups is open to anyone. If you're saying that your local Canvas people told you to do something, that's a different issue that the support at Instructure (who makes Canvas) telling you to go to the forums.
