Subject: square roots that are already worked out

I am looking for a table of square roots that are already worked out.
                                  
Thanks

Hi, Pat.

If you have a spreadsheet program such as Excel, you can build your 
own table very easily. As an example, I used the formula:

     =SQRT($A2*10+B$1)

to build the following table, where the column heading is the units 
digit and the row heading is the higher digits of the number whose 
square root is tabulated.

       0      1      2      3      4      5      6      7      8      9
