How do I simplify a cubed root of a number on the fx-300ES?


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 can I find the square root of 39 on my ti-30xa? Also I would like to know how to find the cube of 9482... Help


Square root of 39: Press 3 9 [square-root] =
[square-root] is the key just to the left of the divide key.

Cube root of 9482: Press 9 4 8 2 2nd [cube-root] =
[cube-root] is the shifted function of the 0 key.

For other roots, you can use the [nth-root] function, the shifted function of the key above the divide key. For example, to calculate the fourth root of 16, press 1 6 2nd [nth-root] 4 =

How would I use this calculator to find a square root?


Two buttons under the shift key-(top left key) and to the right one is the square root key. Just push it and put the number in...it is not manditory to close the parentesis. You can also hit shift before the square root key to get the cubed root.

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)

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][=]

Cube roots


You use the y^x (y to the x) key along with the 2nd function key. That does the opposite operation.

So, let's pick something we know the answer to as an example. How about the cube root of 8? We know 8 = 2 X 2 X 2, so the cube root of 8 will be 2.

Here's how:

8 2nd y^x 3 =

The display will show 2.

The three is the root you want. You can put in any number, with 2 being the square root, 3 the cube root, etc.
