Basic Examples (3)
Display a letter under a square root sign:
| In[1]:= |
Out[1]//DisplayForm= | |
 | |
A SqrtBox form is typically interpreted as a square root:
| In[1]:= |
| Out[1]= |  |
Mathematica represents a square root as a 1/2 power:
| In[2]:= |
Out[2]//FullForm= | |
 | |
The standard formatting for a 1/2-power expression uses SqrtBox:
| In[1]:= |
Out[1]//FullForm= | |
 | |
The formatted result looks like this:
| In[2]:= |
| Out[2]= |  |
