You can get these quickly with Excel, or a similar spreadsheet program. In column A, write 1, 2, 3, ... downward. In Excel, after typing 1 and 2, you can select the two cells and drag the corner (a little black square) downward) to quickly get additional numbers.Next, in cell B1, type:
=sqrt(A1)
Then copy this cell downward.
