Only thing that bugs me about it is that you can only square numbers in scientific mode, and can only use the square root function in Normal mode.
x^.5 is square root. x^(1/10) is 10th root. In scientific mode, press a number, the x^y button, then .5, = and you get square root.169 x^Y .5 = 13
[edit] You can, if you really wanted to, also do it this way in scientific mode:
type this sequence into the claculator where x^y, =, /, log, MS, and MR are visible buttons and 'x' is the number you want the square root of:
'x' log / 2 = MS 10 x^y MR =
Now your square root is shown. :p
[edit2]
The math in that is like this, if you care:
for log, assume bace 10
log('x')/2 = log(TheSquareRootOf'x')
The calculator outputs the result of log(TheSquareRootOf'x') obviously so store that, 'MS', for recalling, 'MR', as the power of 10
what log is, if you don't know, is something like this:
log[baseA](of Q) = R
where
A^R = Q
