The unicode code for square root symbol is 221A. You can define string resource as:

<string name="square_root_symbol">\u221a</string>

And then use it in your button:

<Button ... android:text="@string/square_root_symbol" />

enter image description here

Please see the image I included carefully. It also has horizontal line on top of square root sign. I already have above image placed in my button. Thanks for the suggestion – YuDroid Sep 07 '11 at 05:58
If you don't like the unicode symbol, just make the icon and use it instead of text. – inazaruk Sep 07 '11 at 06:40

Well you can have it like this,

√ - Alt+251

Also look at this link - ASCII

Else you can use the image of square root and include inside a button using the property

android:drawableRight="@drawable/square_root"

Well, you can copy that Image and keep on the Button for working in Android. – Lalit Poptani Sep 07 '11 at 06:26
