DLS C5W4 Quiz - show distorted letters
(Had pass the quiz, but raising issue as can’t give correct ans for this question as equation was not properly visible)

Please check SS

The question appears correctly for me:

@TMosh , Yes but was not correct for me. thats why had attached SS.

I am using,
Google chrome Version 101.0.4951.64 (Official Build) (64-bit)
OS Ubuntu 20.04.4 LTS

One guess would be that this is a problem with your browser. For some reason the MathJax plugin is either not loaded or is not functioning correctly. Do you see any other problems with LaTeX rendering in general or is it just on this one quiz?

@paulinpaloalto All well other than above posted question.

It’s not unusual for browsers to have problems rendering LaTeX notation.
Usually it can be fixed by clearing your browser cache and cookies.

What “other than above posted question” are you referring to ?

@TMosh , All thing working fine expect the posted in question.
No other thing than in original post.
Issue was only with one question
