The symbol can include a horizontal overline or not, depending on the font. To use in a formula, it’s better to use the Office Equation Editor to get good formatting, see below.
How Square Root √ looks in different fonts.
There are a wide range of looks for the Square Root symbol.

Equation Editor
The Square Root symbol, typing square roots with numbers doesn’t look good because the overline can’t go over the number. See these examples using Cambria Math or Aptos fonts:
The Microsoft Office Equation Editor is a better way to make even simple formulas. Go to Insert | Equation then choose one of the Radical options.
With Equation Editor you get nicely formatted square roots with an overline above the number.
Equation Editor will automatically use the Cambria Math font unless you choose another font.
