Question about Office Equipment & Supplies

# I have a Casio fx-83wab. How do I calculate to the power of a fraction? So a number to the power of 1/3 for instance - I've tried the x-1 button with the fraction in brackets after it but that comes up as "syntax error"... Thanks!

Use the general power key that is marked as [^], [Y^x] or [X^y]. Enclose the fractional exponent (1/3) in parentheses.
You can also look for a general root key, marked as [x Root]. To use this key, press the root index (3 for example), followed by [x Root] and then enter the argument. If the index of the root is even ( 2, 4, 6, ...) the argument (inside the root) must be a positive number.

To change from Fraction display to Decimal display on the Casio fx-300ES (and probably other calculators)

1) Press the "SHIFT" button
2) Press the "MODE/SETUP" button
3) Press the "2" button
This Changes it to LINEIO (Decimal)

Doing all of the above but pressing the "1" button instead of the "2" puts it back into MATHIO mode (Fraction)

Hope this Helps
