Question about Texas Instruments TI-86 Calculator

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.

SOURCE: I want the answer to be in decimal form.

Press "MODE"

then scroll down to "Exact/Approx"

select "approximate"

this will have your answers in decimal as default

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

SOURCE: Ti89 answers in fraction form not decimal form

This is what I did. Go to Math/ 9.Algebra/ 5.approx(

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.

Change the output display to MathIO. You may be able to display square roots only: so no cube roots, nor fourth...

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.

Sorry, it does not display results as radicals, let alone simplify them.

Press SHIFT [SETUP] 1 to set the MthIO mode.

Try calculating the square root of 8 (press sqrt 8 =). Do you get 2sqrt2?

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).

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.

It cannot display irrational numbers: it displays a decimal approximation.

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.

To convert a single result from symbolic to decimal form, press the S--D key. To have all results come out in decimal form, press SHIFT MODE 2 to switch to the LineIO mode.
