Odd Notation

[JeffM]

On the link for complex numbers http://www.freemathhelp.com/imaginary-numbers.html

we say So, i = sqrt(-1), or you can write it this way: -1 1/2 or you can simply say: i 2 = -1.

That notation for exponents is used throughout the link. I do not think that notation is standard. If it is a standard, it is so seldom used that I believe it will be hard for students to understand.

No, that is not standard notation for exponents.

It looks like a case where copy-and-paste was not able to hold onto the superscript coding in the original.

Ted will need to manually reformat those missing superscripts.

Thank you for pointing it out.
