First press 3. Then press the carrot to add the exponent. Then you would press the square root button and insert a 5 in it.

Hi, when I'm solving a trignometry exercise, using both degree and radian my Ti Nspire CX (not CAS) will only provide something like a aproximated number instead of giving me the answer in square roots or...


I am afraid you cannot do that. The CX has only two calculation modes AUTO and Approximate, while the CX CAS has these modes and a third one EXACT. That is the one that allows display of result with square roots and the symbol of Pi. Your best choice with the CX is to set the calculation mode to AUTO.

How to get the ti nspire cx to give square root answers


You can not achieve this with the Ti-nspire cx. Only the CAS version will give the square root form. On the CAS there is an option in the settings called "EXACT" under calculation mode. The cx does not have this mode.

Why does the TI-nspire not give complete graphs of cube root and other franctional power functions?


I do not see why it would do that. Maybe you restricted the domain to positive values of the independent variable.
Anyway, my CX CAS has the latest OS version and it draws cube root for positive and negative values of x.
By the way the cube root is made up of one branch only, not 2 like the square root.
Here is a screen capture.

Does my ti-86 solve sq. root problems


Yes, your Ti 86 should solve square root problems. At the HOME screen press [CLEAR] [2nd] [x^2] which gives the (Square Root Symbol) to display at the Home screen. Then enter the number you want the square root of and close the bracket [ ) ] and, press the [ENTER] key.

You can even get the square root of complex numbers too. Select the correct complex format in the mode settings. For example: I'll do one in the rectangular form by enter a number as (a, b). I then will go to [2nd] [MODE] then [Arrow down] 3 times and make sure the RectC is highlighted and selected. Then quit out of the mode settings screen and enter [CLEAR] [2nd] [x^2] [ ( ] [9] [ , ] [ - ] [4] [ ) ] [ ) ] [ENTER], this displays the SQRT((9,-4)) equals (3, 2); The real part is 3 and the imaginary part 2.

How do a take a division problem and square root it on a TI-84 Plus Silver Edition for example 87.34/5 then square root the answer. I can do the math, but how do I take the dvision answer and square...


Two ways:

2ND [square-root] ( 8 7 . 3 4 / 5 ) ENTER

8 7 . 3 4 / 5 ENTER then 2ND [square-root] 2ND ANS ENTER

The first sequence takes the square root of 87.34/5, the second sequence calculates 87.34/5 then takes the square root of the result.

You need the TINspire CAS (Computer Algebra System) to do symbolic manipulations. The Blue TINspire (with TI 84 keyboard) can only perform numerical computations.
If you use variables, the calculator will assign the numerical value stored in the variable.

How do you tak the square root of 64 or the 4 root of any other #


Hi shiny_diamon
Here is a picture of the powers and root functions of your calculator.
1.To calculate the cubic root of a number you use the key combination shown on line 5
Ex: Cubic root of 27
27 [2nd] [3 root x] [EXE]; Should get 3
2. You can use the general root key on line 7 [2nd][x Root y]
Ex: Cubic root of 125
125 [2nd][ x Root y] 3 [EXE] Should get 5
(-125) [2nd][x Root y] 3 [EXE]; Should get -5

3. You can also yse the general power key on line 6: [Y to x], but the degree of the root is entered as a fraction 1/3
Ex: cubic root of -125.
(-125) [Y to x]( 1/3) [EXE]; You should get -5

4. The [Y to x[ key is the one you use to obtain all other roots fourth, fift, tenth, n-th.
Ex: Fourth root of 256
256 [Y to x] (1/4) [EXE]: You should get 4

5. To extract the squqre root of a number you can use the key on the 3rd line [root x] or the general power key on line 6 with exponent 1/2
Exemple square root of 256
256 [Root x] [EXE] should give you 16
256 [Y to x] (1/2) [EXE] should give you 16 also

Hope that helps.

How to get the square root using a ti-30xa calculator?


Come on now....there are dedicated "square" and "square root" keys on the TI-30XA....

Enter your number e.g. 4, then press the "root x" key to get 2...

Press "x squared" key to get the square of 2 = 4

There's the even more useful "y to the power x" key and it's inverse "xth root of y" key.

E.g. Enter 2, then press the "y to the power x" key, then 5, then =, answer is 32 (2 x 2 x 2 x 2 x 2). Starting with 32, pres 2nd then the "y to the power x" key, then 5, then =, answer is 2, the 5th root of 32....
