I am writing an equation using in OpenOffice Writer, but the square root symbol is appearing disconnected in my equation. I have taken a screen shot of the equation in OpenOffice Writer, which can be seen in Figure 1. I was not sure whether or whether not the problem was unique to OpenOffice Writer, so I created an arbitrary equation in OpenOffice Math, and noted that the Square Root symbol was also disconnected, as can be seen in Figure 2. Please note that my OpenOffice version is 4.1.3, and my Operating System is Windows 10 with the build 14393.321.

QUESTION

How can I make the square root symbol connect to the line above the equation contained in the square root?

CODE

Here is the code I am using to create the equations.

Equation in Figure 1:

- Code: Select all Expand viewCollapse view
`r_{~parallel~} = {n^2 cos(%theta) - sqrt{n^2 - sin^2(%theta)}} over`

{n^2 cos(%theta) + sqrt{n^2 - sin^2(%theta)}}

Equation in Figure 2:

- Code: Select all Expand viewCollapse view
`f(x)=sqrt(2x) +3`
