In general, the keystroke combination Ctrl Space gets you out of special
input modes (such as inside a square root, or superscript position, or
subscript position). This works whether you use the palette or use
keyboard shortcuts to produce the special input form (e.g., Ctrl 2 to
get into square-root mode).
Another approach in your situation is this: First type the expression
whose square-root you want. Second select it (with the mouse). Third
click the square-root entry in the Basic Input palette. That will not
only put the original expression under the square-root sign, it will
also automatically return you to normal input mode, outside the
square-root.
The key to understanding the preceding behavior (of first typing the
expression whose square-root is desired) is the little FILLED-IN square
under the square-root symbol in the Basic Input palette. That filled-in
symbol is SelectionPlaceholder. According to Section 1.10.12 of the
Mathematica Book (printed or on-line):
In general, [SelectionPlaceholder] serves as a placeholder
for your current selection. When you press a button that
contains [SelectionPlaceholder], the [SelectionPlaceholder]
is first replaced by your current selection, and only then
is the result inserted into your notebook.
Contrast SelectionPlaceholder with Placeholder, which appears on the
Basic Input palette as a small square that is NOT filled in. The latter
represents input you ordinarily type AFTER you have clicked the palette
button.
