I have substituted r for rho. The greek letter rho may be entered as
esc-r-esc or \[rho] .
The expression below will compute (giving zero unless you define z in
terms of r elsewhere).
Abs[D[z,{r,2}]/(1+D[z,r]^2)^(3/2)]
If it is a question of typesetting the formula, you can enter the above
expression in a text cell, select the cell bracket and follow the menu
path Cell > Convert To > TraditionalForm.
The result below is the "Expression" version.
\!\(\*FormBox[
RowBox[{"\[LeftBracketingBar]",
FractionBox[
FractionBox[\(=A1=D3\^2 z\), \(=A1=D3r\^2\),
MultilineFunction->None],
SuperscriptBox[
RowBox[{"(",
RowBox[{
SuperscriptBox[
RowBox[{"(",
FractionBox[\(=A1=D3z\), \(=A1=D3r\),
MultilineFunction->None], ")"}], "2"],
"+", "1"}], ")"}], \(3/2\)]], "\[RightBracketingBar]
"}], TraditionalForm]\)
