MathJax does not handle multiple exponents

[Marek Lewandowski]

1. Open CKEditor MathJax sample. (i.e. samples/plugins/mathjax/mathjax.html)
2. Doble click any MathJax widget to edit it.
3. Replace its source with following formula:

   10^1^2
   

Expected result:
The formula should be transformed correctly, as an example go to ​online encoder and test it there.

Current result:
The MathJax output is broken.

Additional info:

1. I'm not sure if it's our problem or issue with the external library?
2. Experienced with Chrome 37
3. Also reproduced in CKE 4.3.1

I'm not sure if it's our problem or issue with the external library?

How could this be our issue?

[Marek Lewandowski]

I recall some issue with ampersand. Also I saw that it's parsed correctly in mentioned online encoder. It might use same library as us, and then it would be our issue.

That is simply sth to investigate.

@m.lewandowski wanted to have 10 to the power of 12. I have tested this and entered this code 10^{12} . It worked with our plugin. What is more I have then found below description (point 5): ​http://meta.math.stackexchange.com/questions/5020/mathjax-basic-tutorial-and-quick-reference

It turns out that if you want to insert power having more than one number, you need to put it in curly brackets.

I'm not sure why 10^1^2 works in online builder but the proper syntax is with brackets.

[Marek Lewandowski]

Sounds fair, curly braces in fact are correct way to go.
