Put in the number you want the square root of, then press g [square-root].

g is the blue shift key (third key from the left on the fourth (bottom) row of the keyboard). square-root is on the 1/x key (second key from the left on the second row of the keyboard).

How do i do a number 'to the power of 1/2 or 2/3? cheers Brad


Power 1/2 is the same as square root: You can use the square root key to the left of the square key.
Similarly power 1/3 is the cube root. You use the [SHIFT][Square root] key sequence.
Power 2/3 is the square of the cube root, or the cube root of the square.

More generally, you can use the universal power key, marked with X with a raised white rectangle. It is between X square and log.

Ex: Calculate 15^(2/3)
15 [X with raised rectangle] 2 [/] 3 [)] [=]; the result is 6.082
The last parenthesis closes the left parenthesis introduced by the calculator.
Alternatively you can use the cube root and the x-root selections available under the MATH menu.(selections 4 and 5)

Hello,
Use the square root key accessed after pressing the [2nd] function key.

Press [2nd] [Square root key] 121 [ ) ] [ENTER]. Do not forget the right parenthesis, even if you did not have to enter the left parenthesis.

Hope it helps.
