9.1.2.3 How to prevent LaTeX from hyphenating the entire document?

https://tex.stackexchange.com/landing/r/digest?cta=question&id=5036

9.1.2.4 How do I put text over symbols?

https://tex.stackexchange.com/landing/r/digest?cta=question&id=74125

This is difficult for me to explain, but how do I put words over a symbol? For instance, I want to add words over an equal sign. Anyone know the command/syntax for that? 
Also adding ^ doesn't cut it.....

9.1.2.5 Show equation number only once in align environment

https://tex.stackexchange.com/landing/r/digest?cta=question&id=17528

I want the equation number to be shown only at the last line, or better, somewhere in the middle of all. So instead of (1), (2), ... only (1). 
I use \begin{align} ... \end{align}

I am having the following equation: 
\begin{equation} 
Q(\lambda,\hat{\lambda}) = -\frac{1}{2} P(O \mid \lambda ) \sum_s \sum_m \sum_t \gamma_m^{(s)} (t) \left( n \log(2 \pi ) + \log \left| C_m^{(s)} ...

https://tex.stackexchange.com/landing/r/digest?cta=question&id=40561

What is the easiest way to have 2 lines in some of the cells in a table? 
The only way I can think right now is to actually have 2 separate rows (without the line in the middle) and use \multirow on ...
