Question 289141
You can use the character map, but it may not have everything you're looking for. So I recommend that you simply use the following:


Square root: type sqrt(6) to denote {{{sqrt(6)}}}


Exponent: type x^3 (shift + 6 to get the ^ symbol) to get {{{x^3}}}


Pi: This is just pi. You can also find this in the character map.


Greater than symbol: Simply use ">" (without quotes)


Less than symbol:  Use "<" (without quotes)


Does not equal (or not equal) symbol: Either use =/= or <> to represent something like {{{1<>2}}}. 



In addition to square roots, you have other nth roots (eg cube roots). I'd suggest you type root(3,x) to write out {{{root(3,x)}}}. Fourth roots would then be root(4,y) to get {{{root(4,y)}}} etc.


Also, there is the greater than or equal to symbol. So to write out {{{x>=3}}}, just type x >= 3. In reverse, the less than or equal symbol *[Tex \LARGE \le] is typed out as "<=" (without quotes). For instance, to type {{{y<=5}}}, write y <= 5.


I'm sure that there are a ton of other things that you can't directly enter from the keyboard, but nothing else is coming to mind.
