I have a casio fx-115ES and I want to do a cube root without answering in decimal forms

My square root comes out in the root form like 2 root 3 but when I do a cubed root or more it comes out in decimal form and I want it to come out like before

Sorry, but the fx-115ES can only display square roots in radical form. Cube roots are beyond its symbolic capabilities and will always be in decimal form.

I have a TI-89 Titanium and I have experienced the same problem. HERE IS HOW TO FIX IT:

Goto " MODE " and scroll down the options until you get to
" COMPLEX FORMAT " change that option to " RECTANGULAR " and press ENTER until you exit out of the " MODE " screen. (very important that you press ' enter ' until you exit because if you don't, it will not save your changes. )

SOURCE: When I divide the answer is in fraction form not

There are two options.

1) Whenever you want the answer in decimal form, place a decimal after at least one of the numbers.
For example: instead of using (1/2) use (1/2.)

2) Press the "Mode" button. Scroll down the list that appears until you find "Exact/Approx". If you set it to "Approximate", then it will always give the answer in decimal form. If you set it to "Exact", it will give the answer in fraction form.

SOURCE: TI-89 decimal to fraction

Here is what you do:

1) Press the Mode button.
2) Scroll down the list that appears until you find "Exact/Approx".
3) Change the setting for "Exact/Approx" to Exact.
4) Press enter to save the settings change.

You have three possible settings for "Exact/Approx":
1) Auto - The calculator will try to determine the best format.
2) Exact - The calculator will always give the answer in fraction form.
3) Approximate - The calculator will always give the answer in decimal form.

How do i find the square root of a number on the casio scientific calculator


If, for example, you're getting the square root of 3 as the square root of 3, press the S-D button (just above the DEL) button to convert the symbolic result to a decimal result.

If you want all results to come up in decimal, press SHIFT SETUP 2 to select the LineIO mode.

30xiis decimals square root


In general you cannot. If the square root happens to be an integer (ex: SQRT (4)=2) or a rational number (SQRT(16/9)=4/3) you can convert from one form to the other, but that is the same as converting from a decimal to a fraction.
However you can never convert 1.414213562 (the first 10 digits of SQRT(2)) into the radical SQRT(2). The reason is that root here is an irrational number: its decimal representation is endless and not periodic (non repeating).

Fx-115es radical notation


This calculator can show the results in radical form if it involves square roots. The 4th root of 243 is 3 times the fourth root of 3, which unfortunately is beyond the calculator's capabilities to display in radical form. Try taking the fourth root of 3 (or equivalently, the square root of the square root of 3) and you'll see the calculator display the result in decimal.
