1. How do you read

D=\{\forall x|x\in \Re ,x\neq -5\}

?

Answer:

{\begin{aligned}\overbrace {D} ^{\text{the domain}}\underbrace {=} _{\text{is}}\overbrace {\{} ^{\text{the set}}\underbrace {\forall x} _{\text{of all x}}\overbrace {|} ^{\text{such that}}\underbrace {x\in \Re } _{\text{x is an element of the real number set}}\overbrace {,x\neq -5} ^{\text{where x is not equal to -5}}\end{aligned}}

2. How do you covert from radical form to exponential form?

Answer:

{\sqrt[{m}]{x^{n}}}=x^{\frac {n}{m}}
