In the scientific mode of the Microsoft Windows Calculator application, the square root button (sqrt) disappears.

To mathematically perform the square root function in the scientific mode, use the (x^y) button as the following example demonstrates. To calculate the square root of 144, do the following:
  1. Type 144.
  2. Press the (x^y) button.
  3. Type 0.5 or .5.
  4. Press the equal sign (=) button or another operator button.
The number 12, the square root of 144, should be the result displayed.


Mathematically, you can rewrite the square root of a number (x in the example below) in the following manner to obtain an equivalent equation:
1.  \/ x        is equal to...

2.  \/ x^1      which is equal to...

      (1/2)           (.5)
3.  x^          or  x^
NOTE: The equation in step 3 represents the (x^y) button; therefore, it can be used as the equivalent substitution for the (sqrt) button.
