Square Root (sqrt) in Calculator's Scientific Mode

This article was previously published under Q67184
In the scientific mode of the Microsoft Windows Calculator application, thesquare root button (sqrt) disappears.

To mathematically perform the square root function in the scientificmode, use the (x^y) button as the following example demonstrates. Tocalculate 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 theexample below) in the following manner to obtain an equivalentequation:
      _____1.  \/ x        is equal to...     2_____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.
