It can handle square root but if result requires too much display space it will be displayed as a decimal.As to higher order roots such as cube , 4th and higher they are displayed as decimal. Sorry, there is nothing you can do about it.

How do I get my casio fx300es plus to give me square root answers instead of decimal?


To calculate the square root use the square root key, three rows above the "8" key.
If you want to see the result symbolically, press SHIFT MODE 1 to select the MthIO mode. Bear in mind that the calculator can only show some results symbolically.

Radical calculation


There are limits to what the calculator can display in symbolic form, and roots beyond the second (square roots) are beyond its capabilities. Even something as simple as the cube root of 2 will be displayed numerically.

On my casio fx-82au plus calculator it won't


The capability of these calculators to handle irrational numbers in radical form is limited to square roots. Roots of index other than 2 are always displayed in their decimal representation.
If the calculator IO mode is set to MathIO, square roots will be displayed with the radical symbol. More complicated expressions with square roots might not be preserved and will be given as decimal numbers.

You cannot. The calculator does not have the Natural Display (math display) feature. I have heard that you can flash it with the OS of an FX-9860GII. At your own risk.

How to use the exponent key on a casio fx 300ES calculator ?


The key to use for the square, and the cube are well marked and they share the same physical key (X to 2) or [SHIFT][X to 2]. Similarly the keys to use for the square root and the cube root share the same physical location (the square root key, to the right of the square key).

For any other exponent, including fractions and negative exponents you use the universal power key labeled [X to ] ( X with a raised square).
  1. You enter the base (the number to be raised to a power).
  2. You press the [X to ] power key.
  3. You close the parenthesis (the right one).
  4. You press [=]
Sometimes the result may not be displayed as a decimal number, but as a radical (if you take a root). To make sure it is displayed as a decimal number, in step 4 above, press [SHIFT][=]
